Bronchobiliary Fistula Due To Hydatid Disease of the Liver
(Acta Medical Belgica, 2002) Uzun, K; Özbay, B; Etlik, Ö; Kotan, Ç; Gencer, M; Sakarya, ME
As a complication of hydatid cyst disease of the liver, bronchobiliary fistula is a rare condition and manifests as bilioptysis. We report the case of a 34 year-old man with echinococcosis of the liver who developed a bronchobiliary fistula which manifested as chronic cough and bile stained sputum. A chest X-ray showed an unilateral infiltrate in the costodiaphragmatic angle. Bronchoscopy revealed bile filling the right basal bronchi. Magnetic resonance cystography revealed that the hepatic bile ducts communicated with the right basal pleural space. Percutaneous transhepatic drainage was applied. When the patient was reevaluated, the hydatid cyst had eroded into the pleural space, and a pleural effusion had developed. The condition of the patient deteriorated. Hence, surgical therapy was performed. After surgery, the condition of the patient improved. He was discharged from the hospital in good condition.

Contrast-Enhanced Ct and Mri Findings of Atypical Hepatic Echinococcus Alveolaris Infestation
(Springer, 2005) Etlik, Ö; Bay, A; Arslan, H; Harman, M; Kösem, M; Temizöz, O; Dogan, E
Diagnosis of liver infestation by Echinococcus alveolaris (EA) is based on serological and radiological findings. In this report, we present a 15-year-old girl with atypical hepatic EA infestation showing central punctate calcifications and contrast enhancement on the portal and late phases of CT and MRI. CT showed a hypodense mass involving more than half of the liver with prominent central calcifications. MRI revealed hypointense signal of the infiltrative mass on both T1- and T2-weighted images. Contrast enhancement is a unique finding in hepatic EA infestation that may cause difficulties with diagnosis. MRI may provide invaluable information in the diagnosis of EA infestation of the liver, either by disclosing the infiltrative pattern of infestation without significant effect to vascular structures, or by the signal characteristics.
Deep Intracranial Extension of Squamous Cell Carcinoma of the Scalp
(Wiley-liss, 2005) Etlik, Ö; Bay, A; Izmirli, M; Ugras, S; Yilmaz, N; Turan, A
We report a case of recurrent squarnous cell carcinoma (SCC) of the scalp with deep cerebral invasion in a 15-year-old girl. Plain films and CT showed extensive, full thickness, and skull destruction at the vertex. Gadolinium-enhanced MRI revealed neoplastic invasion of the meninges and both cerebral hemisphers down to the lateral ventricle. This case represents an example of (SCC) imitating a primary brain tumor by exhibiting intracranial extension.
Direct Percutaneous Embolization of a Carotid Body Tumor With N-Butyl Cyanoacrylate
(Blackwell Munksgaard, 2004) Harman, M; Etlik, Ö; Ünal, Ö
We report ultrasound-guided direct percutaneous injection of n-butyl cyanoacrylate for preoperative embolization of carotid body tumor in a 50-year-old patient. Angiographic road map assistance was used for protection of parent arteries during the injection. After embolization, complete devascularization of the tumor was achieved without complications. The tumor was removed surgically with minimal blood loss. This procedure is effective and promising for preoperative embolization of carotid body tumors.
Hepatic Cavernous Hemangiomas -: Patterns of Contrast Enhancement on Mr Fluoroscopy Imaging
(Elsevier Science inc, 2002) Ünal, Ö; Sakarya, ME; Arslan, H; Tuncer, I; Etlik, Ö
Purpose: The purpose of this study was to assess the patterns of contrast enhancement of hepatic hemangiomas on gadolinium-enhanced MR fluoroscopy imaging prospectively. Method: Investigation was performed on a 0.3-T open MR unit. Gadolinium-enhanced MR fluoroscopy images were obtained in 24 patients with 28 hepatic hemangiomas. Each MR fluoroscopy image was obtained in 2 s and MR fluoroscopy lasted for 10-25 min for each investigation. Results: Three patterns of contrast enhancement were observed in 24 patients on MR fluoroscopy images. Four small lesions were not detected on MR fluoroscopy images. Uniform enhancement was seen in nine lesions (29%), peripheral nodular enhancement progressing centripetally to uniform enhancement was seen in nine lesions (29%), and peripheral nodular enhancement with persistent central hypointensity was seen in six lesions (22%). Conclusion: Enhanced MR fluoroscopy technique could obtain dynamic images of hepatic hemangiomas. It can be suggested as a useful technique for the showing of enhancement of hepatic hemangiomas, keeping in mind its low sensitivity in the diagnosis of small hemangiomas.

The Importance of Rigid Nasal Endoscopy in the Diagnosis and Treatment of Rhinolithiasis
(Elsevier Sci Ltd, 2006) Yuca, K; Çaksen, H; Etlik, Ö; Bayram, I; Sakin, YF; Dülger, H; Kiris, M
Objectives: Rhinolithiasis is the presence of mineralized and calcareous formations located in the nasal cavity. They have rare occurrence and can be easily confused with infection or obstruction of tipper airways. If they are undetected for a long time, they may grow large enough to cause of nasal obstruction, mimicking sinusitis. Seven cases of rhinolithiasis were presented, and their diagnosis was made by rigid endoscopic nasal examination. Also computerized tomography scan was used to describe the size and site of the rhinoliths accurately. Our purpose was to determine the role of rigid nasal endoscopy in the diagnosis and the treatment of rhinolithiasis. Methods: In this study, seven cases of rhinolithiasis, who were diagnosed and treated by rigid nasal endoscopy were presented. Results: Between January 2000 and November 2004, seven cases (Four males and three females: age ranged front 8 to 45 years) with rhinolithiasis were diagnosed. The most frequent symptoms were nasal obstruction With purulent rhinorhea. nasal and oral malodor. As complementary examinations, computerized tomography and simple X-ray of paranasal sinuses were used to locate and measure the dimension of calcareous mass, and to reveal possible invasion of the adjacent structures. The removal of rhinolithiasis was done with rigid nasal endoscopy under topical anesthesia in six cases and general anesthesia in one case. Conclusion: Rhinolithiasis is a rare condition but must always be suspected in patients with long standing nasal obstruction, nasal and oral malodor, purulent rhinorrhea and chronic headache.

Incidence of Retro-Aortic Left Renal Vein and Its Relationship With Varicocele
(Springer, 2005) Arslan, H; Etlik, Ö; Ceylan, K; Temizoz, O; Harman, M; Kavan, M
The retro-aortic left renal vein (RLRV) is a malformation characterized by the presence of a vessel that drains the left renal blood up to the inferior vena cava crossing behind the aortic artery. Varicocele is defined as venous dilation of the pampiniform plexus, and the left side is the most commonly affected. Several theories concerning the possible aetiology of varicocele are reviewed in the literature, but RLRV was not mentioned as an aetiologic factor of varicocele. in this study we investigated the percentage of RLRVs and their relation with varicocele. A total of 1,125 contrast-enhanced abdominal CT scans was examined to identify RLRVs. RLRVs were found in nine women (1.6%) and ten men (1.7%). We performed scrotal Doppler ultrasonography (US) for all affected men except one. Varicocele of varying degrees was found in seven of the nine male patients with RLRV (77%). RLRV could be one of the aetiological factors in the development of varicocele, and the cases with RLRV should be examined by scrotal Doppler US for the presence of varicocele.
Late Systolic Wave on Brachial Artery Blood Flow Velocity Pattern in Patients With Coronary Artery Disease and Its Relation To Vascular Stiffness
(Westminster Publ inc, 2001) Güler, N; Eryonucu, B; Bile, M; Etlik, Ö; Erkoç, R; Sakarya, ME
Duplex-Doppler study typically exhibits triphasic brachial artery blood flow velocity pattern in subjects classified as normal without clinically evident atherosclerotic complications, heart disease, hypertension, or diabetes mellitus. In this study, the authors described the late systolic wave on the brachial artery blood flow velocity pattern in patients with coronary artery disease and investigated the relation between late systolic wave and vascular stiffness. Blood flow profile and velocity of the brachial artery were determined noninvasively by ultrasound pulsed-Doppler technique under the guidance of a B-mode ultrasound image in 96 patients with coronary artery disease (CAD). The control group consisted of 23 healthy subjects with no or maximally 2 risk factors (only among age, cigarette smoking, obesity, and gender) for vascular disease. None of the patients and controls had clinical evidence of arterial disorders at upper extremities. In 32 patients (33%) with CAD, a late systolic wave was observed in the brachial artery Doppler study. On the other hand, no late systolic wave was observed in the healthy subjects. In addition, multivessel disease, hypertension, advanced age, diabetes, and smoking were significantly more frequent in patients with the late systolic wave. In conclusion, peripheral arterial abnormalities induced by vascular stiffness may produce alterations in regional wave reflections, and the normal triphasic pattern of the brachial artery blood flow may change by the appearance of the late systolic wave.
Mr Findings in Pericardial Hydatid Cyst
(Tohoku Univ Medical Press, 2003) Sakarya, ME; Irmak, H; Etlik, Ö; Evirgen, Ö; Temizöz, O; Sakarya, N
Pericardial hydatid cyst is rare. We present a 32-year-old man with a pericardial. hydatid cyst. Chest x-ray film showed a spherical mass located left mediastinum. A pericardial cyst with low signal intensity was noted on T1 weighted magnetic resonance (MR) images. The cyst had high signal intensity, but signal intensity of folded parasitic membranes in the cyst were seen lower intensity on T2 weighted MR images. Based on these MR findings, pericardial hydatid cyst was diagnosed. The patient underwent surgical removal of the cyst. Histologic study of the cyst confirmed hydatid cyst diagnosis.

(Amer Roentgen Ray Soc, 2005) Arslan, H; Etlik, Ö; Kayan, M; Harman, M; Tuncer, Y; Temizöz, O
Objective: The objective of our study was to evaluate lactulose solution as a new oral contrast agent with the use of peroral CT enterography to determine the adequacy of luminal distention and conspicuity of the bowel wall. CONCLUSION. Peroral CT enterography performed with lactulose solution is a simple and noninvasive method of evaluating the small bowel by obtaining good distention. It can also be used at routine abdominal examinations as a negative contrast agent instead of iodinated oral contrast medium, especially for CT angiography.
Predictive Value of Magnetic Resonance Imaging Signal and Contrast-Enhancement Characteristics on Post-Embolization Volume Reduction of Uterine Fibroids
(Sage Publications Ltd, 2006) Harman, M; Zeteroglu, S; Arslan, H; Sengül, M; Etlik, Ö
Purpose: To assess the magnetic resonance imaging (MRI) signal and contrast-enhancement features of uterine fibroids before and after embolization, and to determine whether or not there are pre-embolization MRI characteristics that predict the volume reduction of fibroids. Material and Methods: Uterine fibroid embolization (UFE) was carried out in 28 fibroids of 20 patients, all of whom were symptomatic. The patients were prospectively evaluated with T1-weighted, T2-weighted, and gadolinium-enhanced T1 MRI sequences before and 6 months after embolization. The relationship between the characteristics of MRI signal and contrast-enhancement features of fibroids before the procedure and the change in size of the lesions after treatment was investigated. Results: Before embolization, the mean volume of fibroids was 123 cm(3) (8-560 cm(3)). The decrease rate in fibroid volumes was 44.6% (range 7-70%) 6 months after embolization. Volume reduction was more prominent in fibroids that had a high signal intensity on T2-weighted images and a marked contrast enhancement on T1-weighted images (P < 0.001). However, the volume reduction was insufficient in fibroids with high signal characteristics on pre-contrast T1-weighted images (P < 0.001). Conclusion: MRI is an effective method for revealing size and signal changes of fibroids after embolization. MRI signal characteristics and the contrast-enhancement pattern of fibroids before embolization can predict tumor volume reduction after embolization.
The Role of the Mr-Fluoroscopy in the Diagnosis and Staging of the Pelvic Organ Prolapse
(Elsevier Sci Ireland Ltd, 2005) Etlik, Ö; Arslan, H; Odabasi, O; Odabasi, H; Harman, M; Celebi, H; Sakarya, ME
Introduction: The aim of the study is to investigate the efficacy of the magnetic resonance fluoroscopy in the diagnosis and staging of the pelvic prolapse. Materials and methods: The study consisted of 46 patients who were known to have pelvic prolapses from their vaginal examination. Thirty women who underwent vaginal exam and shown not have pelvic prolapse were selected as a control group. Firstly, pelvic sagittal FSE T2 weighted images of all the women were acquired in 0.3 T open MR equipment than sagittal MR-fluoroscopic images using spoiled gradient echo sequences were obtained during pelvic strain. Physical examination and MR-fluoroscopic findings were compared. The relationship between the stages of prolapse established by both of the methods was evaluated statistically with Pearson's correlation analysis. Results: Physical examination and MR findings were very concordant in the diagnosis of pelvic prolapse and statistical correlations in the stages of prolapse were established between both of the methods (P < 0.01 for anterior and middle comportment, P < 0.05 for posterior comportment). Conclusion: We conclude that MR-fluoroscopy is a non-invasive, easily applied, dynamic useful method without contrast agent in the diagnosis and staging of pelvic organ prolapse.
