(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.

(Pergamon-elsevier Science Ltd, 2007) Temizoz, Osman; Etlik, Omer; Sakarya, Mehmet Emin; Uzun, Kursat; Arslan, Halil; Harman, Mustafa; Demir, Mustafa Kemal
We aimed to determine the degree and extent of parenchymal abnormalities on pulmo-CT in patients with emphysema. The study group consisted of 29 patients (18 male, I I female; mean age 57.9. L 13). The diagnosis was based on clinical symptoms, pulmonary function tests (PFT) values, and chest CT findings. All of the patients CT scans were obtained during suspended deep inspiration from the apices to the costophrenic angles. The mean lung attenuation (MLD) and parenchymal abnormalities related to emphysema were quantitatively calculated with tables, histograms and graphics at the whole lung. The lung density measurements revealed a mean density of -898.48 +/- 51.37 HU in patients with emphysema and -825.1 +/- 25.5 HU in control group. In addition, mean percentage of subthreshold attenuation values was found as 12.03 +/- 15.75 and 1.07 +/- 0.83 in patients with emphysema and control group, respectively. Compared with control group, the patients with emphysema had a significantly lower inspiratory MLD (p < 0.05). Additionally, statistically significant correlations were seen between the MLD and percentage of subthreshold values (r = 0.44, p < 0.05). In contrast, there was poor correlation between PFT measurements and the subthreshold values. In conclusion, pulmo-CT is a quick, simple method for quantitative confirmation of the presence of parenchymal abnormalities of lung as mosaic attenuation and should be used in combination with other radiological methods and PFT as it gives additional information to routine examinations in patients with emphysema.

(Professional Medical Publications, 2010) Yuca, Koksal; Avcu, Serhat; Kiroglu, A. Faruk; Etlik, Omer; Cankaya, Hakan; Kiris, Muzaffer
Objective: Eagle's Syndrome is caused by elongation of the styloid process or ossification of the stylohyoid ligament. We aimed to evaluate the contribution of 3-Dimensional Multidetector CT findings on Eagle's syndrome. Methodology: Three-Dimensional Multidetector CT were performed on 13 patients with Eagle's syndrome. Maximum intensity projection (MIP) and volume rendering (VR) images having optimal resolution in all patients were obtained using 3D reconstructions on work-station. Styloid process and its extension, and stylohyoid ligament were evaluated. A styloid processes e '' 3cm were accepted to be longer than normal. We also had a control group of patients which consisted of ten patients who had no complaints of dysphagia, throat pain, or foreign body sensation in the throat. Results: Elongation of the styloid process was revealed by 3D VR imaging in all patients. We found elongated styloid process bilaterally in two patients. Elongation of the styloid process was clearly revealed by 3D VR imaging in high contrast and spatial resolution under the anatomic orientation like conventional X-ray in all patients. The diagnosis of Eagle's syndrome was confirmed surgically in four of 13 patients. Conclusion: We conclude that 3D VR imaging is a valuable diagnostic method in detecting elongated styloid process.

(B C decker inc, 2006) Yuca, Koksal; Bayram, Irfan; Kiroglu, A. Faruk; Etlik, Omer; Cankaya, Hakan; Sakin, Feyat; Kiris, Muzaffer
Objectives: Antrochoanal polyp (ACP) is a benign maxillary sinus polyp that originates from the mucosa of the maxillary sinus, passes through a sinus ostium, and extends into the choana. The common presentation of ACP is unilateral nasal obstruction. The radiographic findings and differential diagnosis of ACPs are discussed by comparing them with data in the literature. Method: This study included 19 (14 male, 5 female; median age 24.5 years, range 8-75 years) surgically treated patients with ACPs diagnosed by clinical examination, nasal endoscopy, and computed tomography. Results: Nasal obstruction was found in all cases. Endoscopic sinus surgery was preferred for removal of the nasal part of ACPs in 13 cases. Only in one case, polypectomy combined with Caldwell-Luc operation and septoplasty was performed. The observed complications were as follows: minor hemorrhage in three cases, mild cheek swelling with pain in two patients, and infraorbital hypoesthesia in one case. Histopathologic examination of ACPs revealed loose mucoid stroma and mucous glands, which were covered by respiratory epithelium. Conclusion: Endoscopic sinus surgery may be indicated in patients with ACPs because the function and capacity of the maxillary antrum are preserved. The greater portion of the antral part of polyp can be removed while leaving the healthy antral mucosa intact.
Hypertrophic Pyloric Stenosis Mr Findings
(Modestum Ltd, 2006) Arslan, Halil; Bay, Ali; Temizoz, Osman; Etlik, Omer; Koseeoglu, Burhan; Kisli, Erol
Infantile hypertrophic pyloric stenosis (IHPS) is a condition affecting young infants, in which the antropyloric portion of the stomach becomes abnormally thickened and manifests as obstruction to gastric emptying. The clinical diagnosis hinges on palpation of the thickened pylorus, or "olive." Abdominal palpation is accurate but not always successful, in such cases, radiologic examinations including US or MRI can be performed. US is the first choice of imaging modality. Unfortunately, in case of difficulty by the sonographic diagnosis of IHPS such as overlying bowel gas, MRI could be useful for the diagnosis.
Internal Jugular Vein Thrombosis Two Different Etiologies
(Modestum Ltd, 2005) Erkoc, Reha; Uzun, Kursat; Yuca, Koksal; Etlik, Omer; Dogan, Ekrem; Sayarlioglu, Hayriye; Cankaya, Hakan
Internal Jugular vein (IJV) thrombosis is a rare entity. It is usually secondary to various etiologies such as catheter, malignancy, trauma, infection and hypercoagulable status. Associated malignancies, either known or occult, are also uncommon and not well documented in the etiology of IJV thrombosis. We reported IJV thrombosis with two different pathologies i.e. malignacy and congestive heart failure. The diagnosis of IJV thrombosis was established with Doppler ultrasound and CT scan. These patients were treated low-molecular-weight heparin and oral anticoagulation. Early diagnosis and appropriate management is important to prevent potentially fatal complications from internal jugular vein thrombosis.
Intracranial Lipomas - a Clinical Study
(Elsevier, 2006) Yilmaz, Nebi; Unal, Ozkan; Kiymaz, Nejmi; Yilmaz, Cahide; Etlik, Omer
Objective: This study aimed to investigate the localization of the lipoma, as well as associated intracranial and extracranial lesions in 14 patients immediately following hospital admission. The pathological findings from the neurological examinations of these patients are also investigated. Methods: Fourteen patients who were admitted to our clinic with a variety of symptoms and diagnosed with intracranial lipoma were included in the study. Problems presented upon admission, neurological findings, and other existing system abnormalities were evaluated. Localization of the lipomas and accompanying pathologies were determined by using computerised tomography and magnetic resonance imaging. Results: The most frequent reasons for admission of patients with intracranial lipomas were: headache 7 (50%), trauma 3 (21.5%), epilepsy 3 (21.5%) and one with symptoms due to the local mass effect of tumor (7%). Although the pericallosal region is accepted as the region where lipomas commonly occur, this study found the most frequent occurrence in the quadrigeminal cistern. Intracranial lipoma calcification was only evident in 1 of the 14 patients. In addition, contrary to the expectations, intracranial and extracranial lesions accompanying lipomas were rare. All patients received systematic treatment. Conclusion: This study showed that intracranial lipomas are more frequent in the quadrigeminal region of the brain; most are asymptomatic, generally caught incidentally; and accompanying intracranial and extracranial pathologies are less common than expected.

Intradural Disc Herniation a Case Report and Review of the Literature
(Modestum Ltd, 2005) Yilmaz, Nebi; Kiymaz, Nejmi; Etlik, Omer; Mumcu, Cigdem
Intradural disc herniation (IDH) is a rare pathology. Intradural disc herniations comprise 0.26-0.30% of all herniated discs. The preoperative knowledge of an intradural herniation is important because it has an influence on the operative strategy. A 55-year-old man suffered from decrease in the motor function of the lower extremities and urinary incontinence. Noncontrast MRI exam showed the intradural disc with caudal migration of an excluded fragment at the L3-4 level. At surgery, the L3 and L4 laminas were removed and after dura had been openned, a nucleus pulposus was seen which compressed the conus medullaris to the right and left of the spinal canal. Every neurosurgeuon involved in spinal surgery must be aware of this rare patology which, when overseen during the intervention, could have disastrous consequences for the patient.
Multiple Brain Abscesses in a Child With Autoimmune Hemolytic Anemia
(Wiley-liss, 2007) Bay, Ali; Yilmaz, Nebi; Nalbantoglu, Ozlem; Yilmaz, Cahide; Etlik, Omer; Oner, Ahmet Faik
A 14-year-old female with autoimmune hemolytic anemia (AIHA) developed an acute hemolytic crisis with acute renal failure under conventional treatment with corticosteroids. Because of the life-threatening situation, we decided to start pulse dose methylprednisolone and also hemodialysis with a femoral catheter placement was performed. Fifteen days after initiating of dialysis subfebrile fever was developed, followed within 2 days with a left hemiparesis. Brain magnetic resonance imaging (MRI) revealed multiple intracerebral abscesses. The clinical picture worsened and the patient died before scheduled surgery for the abscesses.

Primary Hydatid Cyst of the Brain During Pregnancy - Case Report
(Japan Neurosurgical Soc, 2006) Yilmaz, Nebi; Kiymaz, Nejmi; Etlik, Omer; Yazici, Taner
A 26-year-old woman in the 28th week of pregnancy presented with a primary cerebral hydatid cyst manifesting as deteriorating consciousness and weakness in the left arm and leg. Cranial computed tomography revealed an intracranial hydatid cyst. The cyst was surgically removed and albendazole was administered. The patient had a spontaneous vaginal term delivery and no problem was observed in the mother or child. No primary focus was found in the lungs, liver, and other organs. Hydatid cyst is still an important disease. Intracranial hydatid cyst without primary foci in organs such as the liver and lungs is very rare. Primary cerebral hydatid cyst during pregnancy can be successfully treated by surgical and medical intervention.
Radiological and Clinical Course of Pneumonia in Patients With Avian Influenza H5n1
(Elsevier Ireland Ltd, 2007) Bay, Ali; Etlik, Omer; Oner, A. Faik; Unal, Ozkan; Arslan, Halil; Bora, Aydin; Dogan, Murat
Introduction: We evaluated chest X-ray and clinical findings of patients with lower respiratory tract infection due to influenza H5N1 and presented the radiological findings and clinical course of the infection. Materials and methods: Between December 2005 and February 2006, eight hospitalized patients (median age 10, 5-15 years) with avian-flu were evaluated in this study. All patients were evaluated with chest X-ray and four of them with CT scan. Post mortem pathological characterization were also available for three of the patients. Results: A rapidly progressive pneumonia with high mortality rate was observed especially for cases with late admission. The major radiologic abnormalities were extensive pneumonic infiltration with segmental and multifocal distribution, mostly located in lower zones of the lung. No pleural effusion and hilar lymphadenopathy was noted. Conclusion: Avian flu may be presented as rapidly progressive pneumonia. The chest radiography has an important role in diagnosis and should be obtained daily because of rapid change of the findings that may necessitate prompt action. (c) 2006 Elsevier Ireland Ltd.

A Rare Complication of Internal Jugular Vein Cannulation: Horner's Syndrome
(Modestum Ltd, 2005) Dogan, Ekrem; Erkoc, Reha; Sayarlioglu, Hayriye; Etlik, Omer; Uzun, Kursat
Internal jugular vein cannulation has become the preferred approach for temporary vascular access for hemodialysis. Internal jugular vein cannulation is associated with a high rate of successful catheter placement. However, significant complications such as internal carotid artery (ICA) puncture, vessel erosion, thrombosis and infection can occur. We present one case of Horner's syndrome (without arterial punction) occurring following internal jugular venous cannulation. We suggested that, clinicians need to be aware of the risk of Horner's syndrome as a possible complication of percutaneous hemodialysis catheterization via the internal jugular vein and should avoid repeated manipulations
Reconstruction of Wide Scrotal Defect Using Superthin Groin Flap
(Elsevier Science inc, 2006) Atik, Bekir; Tan, Onder; Ceylan, Kadir; Etlik, Omer; Demir, Cengiz
Introduction. Grafts and flaps have been widely used to reconstruct scrotal defects due to Fournier's gangrene. Controversy still exists concerning the use of grafts and flaps because of the low protection provided by the grafts and the high volume of the flaps. We describe the use of an expanded groin flap for scrotum reconstruction. Technical Considerations. Three patients were treated for total scrotal tissue loss using this method. An expander was installed through an incision from the inferolateral aspect of the groin, and superthin flaps obtained after 3 weeks were dissected starting from the medial side. Care was taken during dissection, because the skin was thin on the lateral side, and dissection was performed in a subfascial fashion. Finally, the defect was covered with the lateral part of the expanded flap and the donor site was primarily closed. Conclusions. To cover the testes, both the aesthetic and functional state should be taken into consideration. Therefore, a thin and durable cover is required for scrotal reconstruction. The expanded superthin groin flap possesses these features and is a good option.
