(Soc Romana Ultrasonografe Medicina Biologie-srumb, 2015) Yavuz, Alpaslan; Bora, Aydin; Bulut, Mehmet Deniz; Batur, Abdussamet; Milanlioglu, Aysel; Goya, Cemil; Andic, Cagatay
Aims: To evaluate the feasibility of quantitative analysis of muscle stiffness by Acoustic Radiation Forced Impulse (ARFI) elastography over a course of graduate isometric voluntary contractions. Material and methods: The stiffness of the bilateral biceps muscle of 13 healthy volunteers was measured in real time by ARFI elastography, while the forearm was in neutral-extended position, 90 degree self-flexed positions and 90 degree self-flexed position, with altered weights ranging from 1 to 8 kg placed on flattened palmar surfaces consecutively. The determined increases in biceps muscle stiffness were measured for both arms and correlated with the loadings weights adopted at progressive trial stages. Results: The mean shear wave velocity (SWV) values of biceps muscles in a neutral position, in 90 degree flex position and 90 degree flex position with 1 to 8 kg weights on palmar surfaces were 2.162 +/- 0.302 m/sec, 3.382 +/- 0.581 m/sec, and 3.897 +/- 0.585 to 5.562 +/- 0.587 m/sec, respectively. Significant correlations between the muscle SWV values and related palmar weights and between the SWV values of right and left sides at different trial stages were identified (r=0.951 and r=0.954, respectively). A mutual propagation path of deep regions to entire areas was described to account for the distribution of increase in stiffness with increases in palmar weights. The confidence of method regarding inter-observer difference was confirmed by the correlation analyses of the results (r=0.998). Conclusions: ARFI elastography is a feasible imaging modality for quantifying the stiffness of isometrically voluntarily contracting muscles.
Anterior Hepatic Grooves Accompanied by Chilaiditi Sign: a Retrospective Radiological Analysis of a Neglected Anatomical Fact
(Springer France, 2015) Yavuz, Alpaslan; Batur, Abdussamet; Bulut, Mehmet Deniz; Bora, Aydin; Goya, Cemil; Andic, Cagatay; Olmez, Sehmus
To evaluate anterior hepatic grooves (AHGs) associated with hepato-diaphragmatic mesocolic indentations (Chilaiditi sign) and to delineate the incidence and potential clinical significance of this association. Between November 2011 and June 2014, abdominal computed tomography examinations of 2,314 patients with varied indications were retrospectively reviewed. Patients were surveyed consecutively for the Chilaiditi sign and syndrome, and cases with grooves at the antero-inferior hepatic surface enclosing the adjacent mesocolic indents were determined. The incidence of AHGs and their predominance by gender and age were determined. The potential clinical significance of AHGs associated with Chilaiditi syndrome and their possible effect on liver volume were assessed. The incidences of AHGs were similar between genders (p = .461 and p = .646) and age (p = .113 and .621, respectively) among total cohort and patients with Chilaiditi sign, respectively. There was no significant correlation between AHGs and Chilaiditi syndrome (p = .506); no efficacies of AHGs to liver volume were assessed (p = .413). The AHGs are rare adaptive changes in shape of the liver without a significant effect on liver volume. This overlooked phenomenon is likely derived from the Chilaiditi sign, but has no significant correlation with Chilaiditi syndrome. Future studies with extended series are encouraged to reveal the possible significance of this phenomenon based on concerned surgical interventions.

(Springer, 2014) Bora, Aydin; Alptekin, Cem; Yavuz, Alpaslan; Batur, Abdussamet; Akdemir, Zulkuf; Berkoz, Mehmet
In this study, we aimed to investigate the impact of non-alcoholic hepatic steatosis on the liver volume. As investigating hepatic steatosis, we utilized computed tomography (CT) to determine the degree of steatosis and we utilized hepatobiliary ultrasonography (USG) for densitometry and correlation. As hepatosteatosis group, 35 patients over 18 years of age and whose abdominal CT scans were requested by several clinics and performed routinely were included in this study, and as control group, 40 healthy subjects without hepatosteatosis (clinically and radiologically) and correlated with hepatosteatosis group in terms of age and gender were included in this study. CT densitometry and liver attenuation index (LAI) of all individuals who participated in our study were calculated, and contrast images of patients were transferred to CT-Volume Software (Siemens Syngo Multimodality Workplace; Version VE52A). In this study, interactive and automated volume measurement techniques were used together. The volumes were measured separately in patient and control group. In this study for each stage in USG, there was found a direct correlation in terms of LAI and volume, and this correlation was statistically significant (p < 0.01). Furthermore, statistical significance between size and USG stage draws attention (p < 0.05). A significance relationship between USG stage and age could not be determined. As a result, we have reached the conclusion that CT densitometry can be used as an assistive technique along with USG to determine the degree of steatosis in the non-alcoholic fatty liver disease, and there is a positive linear correlation between the liver size and volume, and liver volume increases in the non-alcoholic fatty liver disease.
Brain Magnetic Resonance Imaging and Magnetic Resonance Spectroscopy Findings of Children With Kernicterus
(int Scientific information inc, 2015) Sari, Sahabettin; Yavuz, Alpaslan; Batur, Aabdussamet; Bora, Aydin; Caksen, Huseyin
Background: The term kernicterus, or bilirubin encephalopathy, is used to describe pathological bilirubin staining of the basal ganglia, brain stem, and cerebellum, and is associated with hyperbilirubinemia. Kernicterus generally occurs in untreated hyperbilirubinemia or cases where treatment is delayed. Magnetic resonance imaging (MRI)-based studies have shown characteristic findings in kernicterus. The objective of our study was to describe the role of 1H magnetic resonance spectroscopy (MRS) in demonstrating these metabolic changes and to review conventional MRI findings of kernicterus. Material/Methods: Forty-eight pediatric cases with kernicterus were included in this study. MRI and MRS examinations were performed on variable dates (10-29 days after birth). NAA, Cr, Cho, NAA/Cr, NAA/Cho, and Cho/Cr values were evaluated visually and by computer analysis. Results: There was no statistically significant difference between the NAA and Cho levels in the acute kernicterus patients and the control group (healthy patients), whereas both were significantly elevated in the chronic kernicterus patients. Both the mean NAA/Cr and Cho/Cr ratio values were significantly higher in the acute and chronic cases compared to the control group. The NAA/Cho ratio value was statistically lower in the acute cases than in the control group while it was similar in the chronic cases. Conclusions: Conventional MR imaging and 1H-MRS are important complementary tools in the diagnostics of neonatal bilirubin encephalopathy. This study provided important information for applying these MR modalities in the evaluation of neonates with bilirubin encephalopathy.
A Case of Adem Mimicking Cerebral Adrenoleukodystrophy Based on Supratentorial Mri Findings
(Aves, 2014) Beyazal, Mehmet; Unal, Ozkan; Yilmaz, Sanem; Bora, Aydin
A 9-year-old male admitted for syncope also had the complains of pain and numbness in his legs and frequent falling down. There was a history of upper respiratory tract infection 10 days before. On neurologic examination, paraparesia and fall a sleep were identified. On magnetic resonance imaging, the symetric signal increases were seen in biparieto-occipital white matter intented to corpus callosum at T2-weighted sequences and cytotoxic edema was seen at diffusion-weighted images. Heterogeneous contrast enhancement was seen on these areas. In addition, at the C7-Th5 vertebrae levels, spinal cord had diffuse increased signal intensity and contrast enhancement. Acute disseminated encephalomyelitis was thought based on clinical and radiological findings. Steroid therapy was started. Significant improvement was shown after treatment. On 2-year follow-up, there was no recurrence. In conclusion, it must be kept in mind that acute disseminated encephalomyelitis can rarely present with biparieto-occipital involvement which extends to corpus callosum and can mimic adrenoleukodystrophy. For the differential diagnosis butterfly glioma, tumefactive demyelinating lesions or multiple sclerosis should be considered.

(Aves, 2009) Unal, Ozkan; Kartum, Alp; Avcu, Serhat; Etlik, Omer; Arslan, Halil; Bora, Aydin
PURPOSE The aim of this study was cerebrospinal flow quantification in the cerebral aqueduct using cine phase-contrast magnetic resonance imaging (MRI) technique in both sexes and five different age groups to provide normative data. MATERIALS AND METHODS Sixty subjects with no cerebral pathology were included in this study. Subjects were divided into five age groups: <= 14 years, 15-24 years, 25-34 years, 35-44 years, and >= 45 years. Phase, rephase, and magnitude images were acquired by 1.5 T MR unit at the level of cerebral aqueduct with spoiled gradient echo through-plane, which is a cine phase-contrast sequence. At this level, peak flow velocity (cm/s), average flow rate (cm/s), average flow (L/min), volumes in cranial and caudal directions (mL), and net volumes (mL) were studied. RESULTS There was a statistically significant difference in peak flow between the age group of <= 14 years and the older age groups. There were no statistically significant differences in average velocity, cranial and caudal volume, net volume, and average flow parameters among different age groups. Statistically significant differences were not detected in flow parameters between sexes. CONCLUSION When using cine-phase contrast MRI in the cerebral aqueduct, only the peak velocity showed a statistically significant difference between age groups; it was higher in subjects aged <= 14 years than those in older age groups. When performing age-dependent clinical studies including adolescents, this should be taken into consideration.
Coexistence of Neurofibromatosis Type-1, Left Internal Carotid Artery Hypoplasia and Left Phytisis Bulbi
(Galenos Publ House, 2011) Avcu, Serhat; Akdeniz, Huseyin; Unal, Ozkan; Arslan, Harun; Bora, Aydin
Congenital abnormalities of the internal carotid artery (ICA) are extremely rare and aplasia/hypoplasia of the ICA associated with other congenital malformations is uncommon. An 8-year-old male patient was admitted to our hospital for extreme nervousness, attention problems and hyperactivity. On MR examination, left phytisis bulbi, left frontal lobe atrophy, assymmetric dilataion in the left lateral ventricle and hamartomas in both globus pallidi, right thalamus, and bilateral cerebellar hemispheres posterior to the fourth ventricle were observed. Left ICA was observed as hypoplastic in the cervical and cranial MR-angiography. Left MCA and ACA could not be visualised. Left carotid canal hypoplasia and left sphenoidal bone dysplasia were detected on CT. As far as we know, only 4 cases with concomitancy of ICA hypoplasia-NF Type-1 have been reported up to the present. In our case, in addition, phytisis bulbi is accompanying this coexistence.
Comparison of Computed Tomography Densitometry and Shear Wave Elastography Velocity Measurements for Evaluation of the Liver Volume in the Nonalcoholic Fatty Liver Disease
(E-century Publishing Corp, 2016) Bulut, Mehmet Deniz; Ozdemir, Hayrullah; Bora, Aydin; Yavuz, Alpaslan; Arslan, Harun; Batur, Abdussamet; Ozgokce, Mesut
Purpose: The aim of the present study is to evaluate and compare the values of velocities measured by the shear wave elastography (SWE), and those of the liver attenuation index (LAI) determined by the computerized tomography (CT) densitometry, in the nonalcoholic fatty liver disease (NAFLD). In other words, we aimed to compare the values of density measured by CT and the stiffness determined by elastography, in the liver steatosis. In addition, it is to investigate the effect of NAFLD on the liver volume. Materials and methods: Forty five cases with hepatosteatosis who had undergone abdominal CT and 50 individuals who did not exist with fatty liver clinically and radiologically, were investigated by ultrasonography (US) and SWE. The liver and spleen attenuation values were then measured in the images of non-contrast CT, and the LAI indices were calculated. Contrast images of abdomen were processed by the CT-Volume software and measurements of liver volume were performed using the interactive and automatic liver segmentation techniques together. Values of the liver volume, LAI, liver dimensions, and the shear wave velocities were determined and recorded in the patients with hepatosteatosis and controls; statistical comparisons were performed then. Results: In the nonalcoholic fatty liver, the mean value of velocity measured by SWE was found to be 1.08 (+/- 0.11) m/s, and that of LAI measured by CT densitometry was 13.68 (+/- 10.6). No correlation was observed between these two parameters (P>0.05). A high statistically significant difference between the patient and control groups in terms of the liver volume, LAI values and liver size has been observed (P<0.01). Direct correlations existed between the liver volume and LAI values, and the grades in US, and highly significant differences were determined (P<0.01). The mean values of the liver volume in the patient and control groups were determined to be 1917.4 (+/- 425.9) cm(3) and 1311.4 (+/- 241.4) cm(3), respectively. A high statistically significant difference between the groups in terms of liver volumes has been observed (P<0.01). Conclusion: In our study, we determined no correlation between the values of velocity measured by SWE, and the values of LAI measured by CT densitometry, in the NAFLD (P>0.05). This result indicates that there is no relation between the degree of stiffness evaluated by SWE, and the attenuation values measured by CT densitometry, in the non-alcoholic fatty liver. The liver volume was found to increase in NAFLD. We concluded that the CT densitometry can be used as an auxiliary technique associated with the US, in determining the degree of steatosis in NAFLD.

(Wiley-blackwell, 2016) Karaman, Erbil; Arslan, Harun; Cetin, Orkun; Sahin, Hanim Guler; Bora, Aydin; Yavuz, Alparslan; Akbudak, Ibrahim
AimThe aim of this research was to study and compare placental elasticity with acoustic radiation force impulse (ARFI) elastography in pre-eclamptic and normal pregnancies. MethodsA total of 107 singleton pregnancies in the third trimester (38 healthy control subjects, 34 patients with gestational hypertension, and 35 pre-eclampsia patients) were included in the study. ARFI elastography was used to determine the placental elasticity in the three predetermined regions of the placenta (the fetal edge, maternal edge, and central part of the placenta). The obstetrical data regarding grayscale and Doppler ultrasonography and perinatal outcomes were reviewed. A mean placental shear wave velocity cut-off value that predicts the presence of pre-eclampsia was determined. ResultsThe shear wave elasticity values in the pre-eclampsia group in all three regions were significantly higher than in the gestational hypertension and healthy control groups (P=0.001). The most significant difference was found in the peripheral edge of the placenta from the fetal surface in the pre-eclampsia group (P=0.001). ConclusionThe stiffness of the placenta determined by the ARFI technique is significantly higher in pre-eclampsia patients. ARFI elastography of the placenta might be used as a non-invasive and easy method in the diagnosis and evaluation of pre-eclampsia as a supplement to the already existing methods.

(int Scientific information, inc, 2016) Bulut, Mehmet Deniz; Alpayci, Mahmut; Senkoy, Emre; Bora, Aydin; Yazmalar, Levent; Yavuz, Alpaslan; Gulsen, Ismail
Background: Because loss of cervical lordosis leads to disrupted biomechanics, the natural lordotic curvature is considered to be an ideal posture for the cervical spine. The vertebral arteries proceed in the transverse foramen of each cervical vertebra. Considering that the vertebral arteries travel in close anatomical relationship to the cervical spine, we speculated that the loss of cervical lordosis may affect vertebral artery hemodynamics. The aim of this study was to compare the vertebral artery values between subjects with and without loss of cervical lordosis. Material/Methods: Thirty patients with loss of cervical lordosis and 30 controls matched for age, sex, and body mass index were included in the study. Sixty vertebral arteries in patients with loss of cervical lordosis and 60 in controls without loss of cervical lordosis were evaluated by Doppler ultrasonography. Vertebral artery hemodynamics, including lumen diameter, flow volume, peak systolic velocity, end-diastolic velocity, and resistive index, were measured, and determined values were statistically compared between the patient and the control groups. Results: The means of diameter (p=0.003), flow volume (p=0.002), and peak systolic velocity (p=0.014) in patients were significantly lower as compared to controls. However, there was no significant difference between the 2 groups in terms of the end-diastolic velocity (p=0.276) and resistive index (p=0.536) parameters. Conclusions: The present study revealed a significant association between loss of cervical lordosis and decreased vertebral artery hemodynamics, including diameter, flow volume, and peak systolic velocity. Further studies are required to confirm these findings and to investigate their possible clinical implications.

(Saudi Med J, 2017) Tatlisumak, Ertugrul; Asirdizer, Mahmut; Bora, Aydin; Hekimoglu, Yavuz; Etli, Yasin; Gumus, Orhan; Keskin, Siddik
Objectives: To define the dimensions of the frontal sinus in groups standardized for age and gender and to discuss the reasons and the effects of the variations. Methods: Frontal sinus measurements were obtained from paranasal CT scans of 180 males and 180 females in the Radiology Department of Dursun Odabas Medical Center of Yuzuncu Yil University, Van, which is located in Eastern Turkey, between February and March 2016. The width and height of sinuses were measured on a coronal plane, and the anteroposterior length was measured on an axial plane. Volumes were calculated using the Hospital Information Management Systems and Image Archiving and Management System program. The Statistical Package of the Social Science version 13 was used for statistical analyses. Results: We determined differences in the frontal sinus measurements of different age groups in a Turkish adult population. Frontal sinus dimensions were usually higher in females and lower in males after 40-49 years of age than their younger counterparts, but the measurements were lower in females and higher in males in 70 <= years of age group than 60-69 years of age. Left frontal sinus was dominant in young age groups but right frontal sinus was dominant in groups 40-49 years of age or older. Conclusion: We observed crossing of the measurements between the different age groups, which we could not find clear explanations. The results of such studies may affect forensic identification from frontal sinus measurements.

(Bayrakol Medical Publisher, 2020) Orak, Suat; Bora, Aydin; Yokus, Adem; Ozkacmaz, Sercan; Senkoy, Emre
Aim: The aim of this study was to compare carotid intima-media thickness (IMT) and common carotid artery-vertebral artery flow volumes in ankylosing spondylitis patients with age and sex-matched healthy controls. Materials and Methods: Fifty patients with ankylosing spondylitis (study group) and 50 healthy volunteers (control group) were included in the study. At first, carotid intima-media thickness (IMT) measurements were performed in supine-neutral position by B-mode ultrasonography (US). Afterwards, common carotid and vertebral artery flow volumes were calculated by Doppler US in the neutral, right rotational, and left rotational positions. Results: Carotid IMT was significantly higher in the study group according to the control group (p=0.001). The common carotid artery (CCA) and vertebral artery (VA) flow volumes in the neutral position were similar between the two groups. There was no significant difference in CCA flow volumes between the groups in right and left rotational positions (p>0.05). Right vertebral artery and total vertebral artery flow volumes in the right rotational position were significantly lower in the study group (p=0.022 and p=0.005 respectively). In the left rotational position, left vertebral artery and total vertebral artery flow volumes were significantly lower in the study group when compared with the control group (p=0.001). Discussion: In our study, carotid IMT was significantly higher in patients with AS compared to healthy controls. Besides, significant volume decreases in vertebral artery flow volumes were detected in the study group in rotational positions.
Hepatic Artery Pseudoaneurysm: Delayed Presentation After a Blunt Trauma
(int Scientific information inc, 2015) Batur, Abdussamet; Yavuz, Alpaslan; Toktas, Osman; Bora, Aydin; Bulut, Mehmet Deniz
Background: Ruptured hepatic artery pseudoaneurysm is a rare condition that is life-threatening if not diagnosed and treated rapidly. We present a case of a spontaneously ruptured hepatic artery pseudoaneurysm that occurred after a blunt trauma, and provide a review of the current literature on this topic. This case study demonstrates a spontaneously ruptured hepatic artery pseudoaneurysm which emerged following a blunt trauma and it also presents current literature studies on the topic. Case Report: A man at the age of 34 years with blunt trauma dating back to 1.5 month was admitted to the emergency department of a hospital with hematemesis and epigastric tenderness. He also had a duodenal ulcer, blood in the gastric lumen and a large pseudoaneurysm that developed from the left hepatic artery. Soon after the diagnosis, the patient worsened and underwent distal gastrectomy and cholecystectomy that included removing the bleeding aneurysm. Conclusions: Ruptured hepatic artery pseudoaneurysm stands as a deadly condition which has to be diagnosed and managed as soon as possible. Physicians need to take aneurysms of abdominal arteries into consideration after routine diagnostic practises as long as the cause of gastrointestinal haemorrhage is unidentified.
Hepatic Metastases of Primary Jejunal Carcinoid Tumor: a Case Report With Radiological Findings
(Medknow Publications & Media Pvt Ltd, 2009) Avcu, Serhat; Ozen, Ozkan; Bulut, Mehmet Deniz; Bora, Aydin
Context: Carcinoid tumors represent a group of well-differentiated tumors originating from the diffuse endocrine system outside the pancreas and thyroid. The overall prevalence of carcinoid tumors in the United States is estimated to be one to two cases per 100,000 persons. Various sites of origin of this neoplasm are appendix -3 0-45%, small bowel - 25-35% (duodenum 2%, jejunum 7%, ileum 91%, multiple sites 15-35%), rectum 10-15%, caecum - 5%, and stomach - 0.5%. Liver metastases from jejunal and ileal carcinoids are generally hypervascular. Case report: Here we report a case of primary jejunal carcinoid tumor in a 66-year-old woman metastasizing to liver with ultrasonography, computed tomography, and diffusion-weighted magnetic resonance imaging (DWI) findings. Conclusion: Primary jejunal carcinoid tumor is a rare entity. DWI can help in the differential diagnosis of hepatic hypervascular metastatic mass lesions from benign ones, as well as in the diagnosis of carcinoid tumor.

(Elsevier Science inc, 2015) Yavuz, Alpaslan; Bora, Aydin; Kurdoglu, Mertihan; Goya, Cemil; Kurdoglu, Zehra; Beyazal, Mehmet; Akdemir, Zulkuf
Study Objective: To review the main sonographic and magnetic resonance imaging manifestations of Herlyn-Werner-Wunderlich syndrome, characterized by uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis, and to discuss the value of techniques for its diagnosis and treatment. Participants: Thirteen patients with Herlyn-Werner-Wunderlich syndrome referred to our department with acute abdomen were identified for the period from 2009-2012. Design: Retrospective chart review. Setting: Two tertiary academic centers. Interventions: None. Main Outcome Measures: The evaluation of the clinical features, ultrasonography and magnetic resonance imaging findings, and the treatment protocols. Results: Ultrasonographic evaluation of didelphic or double uterus in 10 and bicomuate-bicollis uterus in 3 patients with hematocolpos or hematometrocolpos associated with agenesis of the ipsilateral kidney revealed the diagnosis. In 10 patients, magnetic resonance imaging provided extra information. In 1 patient, a 25-week pregnancy was additionally detected and follow-up was suggested. Seven patients underwent surgical excision of the septum and drainage of the obstructed vagina. Total hysterectomy and hemicolpectomy were performed in 1 patient with 2 children suffering from severe chronic pelvic pain due to pelvic inflammatory disease. Conclusions: Despite its rarity, accurate diagnosis and morphologic description of Herlyn-Werner-Wunderlich syndrome with radiologic modalities are of importance in relieving the clinical complaints by enabling the suitable surgical treatment to be identified.
Hydrocarbon Pneumonitis; Clinical and Radiological Variability
(derman Medical Publ, 2015) Sertogullarindan, Bunyamin; Bora, Aydin; Sayir, Fuat; Ozbay, Bulent
Aspiration of hydrocarbons causes respiratory pathologies from simply to critical. Our aim is to attract attention to clinical and radiological variability in these cases. We presented a 22-year old young case exposed to diesel fuel by accidental aspiration. Three days after the aspiration, because of clinical deterioration, he was admitted to our emergency clinic. In the chest radiograph on admission showed infiltration in the right middle lobe. But a right lower lobe atelectasis emerged two days later. Bronchoscopy revealed inflamed and hyperemic mucosa and no bronchial obstruction. No secondary bacterial pneumonia was seen. The patient was treated with systemic steroids and antibiotics. After two weeks of treatment there was complete clinical improvement and significant radiologic regression. In the hydrocarbon aspiration cases clinical picture is variable. Radiological picture may develop with a delay. Unless there is a new evidence for an important complication, the steroid treatment should be followed.
Imaging Findings for Bilateral Giant Vestibulocochlear Schwannoma
(Acad Medical Sciences I R Iran, 2016) Bulut, Mehmet Deniz; Yavuz, Alpaslan; Bora, Aydin; Gulsen, Ismail; Batur, Abdussamet
Neurofibromatosis type 2 mostly develops with multiple neoplasms of the central and penpheral nervous system and is associated with ocular abnormalities The presented case is a 19-year-old female patient with bilateral vestibulocochlear schwannomas in both pontocerebellar corners, intradural intra-e)dramedullary masses, and multiple neurofibromas in the spinal canal. The clinical picture for NF-2, also called central neurofibromatosis, is completely different from von Recklinghausen disease. Untreated Bilateral vestibulocochlear schwannoma may cause hydrocephalus in NF-2, and lead to death. Therefore, it is recommended to carefully monitor and treat Bilateral vestibulocochlear schwannonia in accordance with its stage.
Mri of Omphalopagus Conjoined Twins With a Dandy-Walker Malformation: Prenatal True Fisp and Haste Sequences
(Aves, 2010) Uenal, Oezkan; Arslan, Halil; Adali, Ertan; Bora, Aydin; Yildizhan, Recep; Avcu, Serhat
Conjoined twins are an extremely rare congenital malformation without any known genetic predisposition. Omphalopagus twins are the second most common variety of conjoined twins and usually are joined at the umbilicus. We present omphalopagus conjoined twins demonstrated with true FISP (fast imaging with steady-state procession) and HASTE (half-Fourier acquisition single-shot turbo spin-echo) magnetic resonance imaging (MRI) sequences, which showed Dandy-Walker malformation in one of the pair. To our knowledge, this is the first case of conjoined twins with this malformation, which was diagnosed with ultrafast MRI.
Necrotizing Brucella Epididymoorchitis: Magnetic Resonance Imaging Findings
(Nobel Ilac, 2014) Beyazal, Mehmet; Ozkacmaz, Sercan; Unal, Ozkan; Yavuz, Alpaslan; Bora, Aydin
Brucella epididymoorchitis (BEO) had been reported up to 20% of patients with brucellosis. Althought it has a good response to spesific antibiotherapy, the delay in diagnosis and in treatment may result in necrosis and abscess formation. Ultrasonography is the basic imaging method for screening of scrotal diseases such as BEO. In literature, there are many studies which present sonographic and magnetic resonance imaging (MRI) features of scrotal and testicular lesions. However; there is no any sufficient publication in which the findings of BEO have been defined on MRI examination. In this report, we presented a patient who had unilateral necrotizian epididymoorchitis and testicular abscess resulted from brucellosis with MRI findings and we also discussed the contribution of MRI to the management of the disease.
