Öğe Bronchocele: Demonstration By 3D Volume Rendering Imaging with Multidetector Computed Tomography: Case Report(ORTADOGU AD PRES & PUBL CO, 2011) Sakarya, Mehmet Emin; Ceran, Sami; Koc, Osman; Ozbek, Orhan; Karabekmez, Leman G.; Odev, KemalCongenital bronchial atresia (CBA) is a rare congenital abnormality of the lung. It results from a congenital focal obliteration of a proximal segmental or sub-segmental bronchus with normal development of distal structures. Because of proksimal bronchial stenosis, the distal bronchi became filled with mucus and form a bronchocele. Three dimensional (3D) volume rendering (VR) imaging was performed with 64-slice multidetector computed tomography (MDCT) equipment in a patient with CBA and bronchocele. 3D VR images clearly revealed branching nonenhancing tubular structure and the adjacent lung with features of air trapping. A diagnosis of bronchocele was made radiologically. We report a case of bronchocele documented by 3D image reconstruction and VR images using 64-slice MDCT. In this article we report that, the radiologic findings of the broncocele can be shown more clearly with 3D VR technique than standan CT imaging.Öğe Clinical and Imaging Findings in the Alveolar Echinococcosis(BENTHAM SCIENCE PUBL LTD, 2009) Emlik, Dilek; Odev, Kemal; Kiresi, Demet A.; Karakose, Serdar; Gok, MehmetAim: To review the imaging features of alveolar echinococcosis in eight patients with involvement of different organs. Material and Methods: Ultrasound (US) and computed tomography (CT) examinations were performed in all patients, and magnetic resonance imaging (MRI) and color Doppler ultrasound (CDUS) were performed for two patients. Three patients had involvement of only the liver; two had involvement of lung and liver; one had involvement of only the lung; one had involvement of liver and sternum; and one had lung, liver, and adrenal involvement. The diagnosis was confirmed by histopathologic examination in all patients. Results: The lesions located in the liver were generally seen as heterogeneous hypoechogenic on US, hypodense on CT, and hypointense solid masses on MRI. These masses included necrosis and calcifications. Vascular flow on CDUS and contrast enhancement on CT and MRI were not observed in any of the lesions. On CT, lung lesions were seen as multiple, nodular, well-defined or ill-defined opacities; some had cavitations caused by necrosis. Conclusion: Knowledge of imaging characteristics of alveolar echinococcosis makes it possible to provide an early diagnosis radiologically. In addition, radiologic findings have an important role in the follow-up. Ultrasound, CT, and MRI are complementary methods in the diagnosis of alveolar echinococcosis.Öğe Comparison of Ventilation-Perfusion Scintigraphy With MR Angiography in Patients With Swyer-James Syndrome(LIPPINCOTT WILLIAMS & WILKINS, 2013) Serdengecti, Mustafa; Sakarya, Mehmet E.; Ilerisoy, Zeynep Y.; Odev, KemalPurpose: The aim of this study was to establish the value of magnetic resonance angiography (MRA) in diagnosing) Swyer-James syndrome (SJS) and to compare MRA and ventilation-perfusion (V/Q) scan results in patients with established SJS. Methods: The V/Q scans and the MRA findings of 22 lungs of 11 patients with SJS (6 males, 5 females; age range: 17-69 years, mean: 38.4 years) were retrospectively studied. The perfusion scan was performed after the injection of Tc-99m macroaggregated albumin. After 2 days, the ventilation scan was performed by using Tc-99m diethylene triamine penta-acetic acid aerosol. The MRA was performed with a 1.5 T magnetic resonance unit. We compared the MRA and V/Q scan findings of the lungs of the patients. Results: The V/Q scans showed the characteristic pattern of a matched V/Q defect on the affected lungs. The MRA displayed a smaller pulmonary artery and markedly poor peripheral vasculature on the affected side in all patients. The MRA had a sensitivity of 84.6%, a specificity of 100% for the detection SJS. Interobserver variability was minimum as indicated by a weighted kappa statistic of 0.818. Conclusion: This study indicates that the MRA is a fast, accurate, without radiation, and noninvasive technique for supporting the diagnosis of SJS. But, V/Q scans showed additional segmental perfusion/ventilation abnormalities on contralateral lung to reveal the segmental involvement of SJS. As a result, the MRA has no more any extra advantages for patient management.Öğe Differential diagnosis of dumbbell lesions associated with spinal neural foraminal widening: Imaging features(ELSEVIER IRELAND LTD, 2009) Kivrak, Ali Sami; Koc, Osman; Emlik, Dilek; Kiresi, Demet; Odev, Kemal; Kalkan, ErdalComputed tomography (CT) and magnetic resonance imaging (MRI) reliably demonstrate typical features of schwannomas or neurofibromas in the vast majority of dumbbell lesions responsible for neural foraminal widening. However, a large variety of unusual lesions which are causes of neural foraminal widening can also be encountered in the spinal neural foramen. Radiologic findings can be helpful in differential diagnosis of lesions of spinal neural foramen including neoplastic lesions such as benign/malign peripheral nerve sheath tumors (PNSTs), solitary bone plasmacytoma (SBP), chondroid chordoma, superior sulcus tumor, metastasis and non-neoplastic lesions such as infectious process (tuberculosis, hydatid cyst), aneurysmal bone cyst (ABC), synovial cyst, traumatic pseudomeningocele, arachnoid cyst, vertebral artery tortuosity. In this article, we discuss CT and MRI findings of dumbbell lesions which are causes of neural foraminal widening. (C) 2008 Elsevier Ireland Ltd.

Surgical resection was chosen for accurate diagnosis and treatment of the huge mediastinal masses extending into the pleural cavity. Methods Records were reviewed for eight patients who had the diagnosis of huge benign mediastinal masses and who underwent operation; details of the patients and operations were recorded. Results Mean age was 34.5 (range 22 to 44) years, and male-to-female ratio was 2:6. Computed tomography and magnetic resonance imaging (MRI) were used to evaluate the location and extent of the abnormality and to characterize the tissue components of the mass. Most of the tumors were located in the posterior mediastinum. The most frequent presenting symptom was exertional dyspnea. The majority of cases underwent posterolateral thoracotomy, and complete resection was possible in seven patients. Partial resection could only be performed in one. The mean diameter of the resected masses was 15 x 10 cm. Histopathologic examination revealed 3 neurogenic tumors, 2 teratomas, 1 thymolipoma, and 1 ectopic thyroid, and 1 hemangioma. Minor complication was seen in two cases. Conclusion The presurgical thoracic MRI provided correct diagnosis along with radiologic characterization and topography. Surgery must be the preferred treatment in huge benign mediastinal masses.Öğe A giant renal artery aneurysm presenting as a calcified hydatid cyst(MA HEALTHCARE LTD, 2019) Koplay, Mustafa; Uysal, Emine; Kelesoglu, Kazim S.; Odev, Kemal[Abstract not Available]Öğe Multitechnique Evaluation of Renal Hydatid Disease(AMER ROENTGEN RAY SOC, 2009) Turgut, Ahmet Tuncay; Odev, Kemal; Kabaalioglu, Adnan; Bhatt, Shweta; Dogra, Vikram S.OBJECTIVE. Hydatid involvement of the kidney accounts for only 2-4% of all cases of hydatid disease. The purpose of this article is to review the imaging features of hydatid disease of the kidney and thus show the role of radiography, excretory urography, sonography, CT, and MRI in the diagnosis of hydatidosis. CONCLUSION. The radiologist should be familiar with the imaging findings of hydatid disease because early diagnosis is important for more appropriate treatment.Öğe Partially thrombosed multiple pulmonary artery aneurysm secondary to Behcet disease(HINDAWI LTD, 2015) Guler, Ibrahim; Odev, Kemal; Tunc, Recep[Abstract not Available]Öğe Percutaneous injection sclerotherapy with tetracycline hydrochloride in simple renal cysts(SPRINGER, 2008) Kilinc, Mehmet; Tufan, Osman; Guven, Selcuk; Odev, Kemal; Gurbuz, RecaiObjectives Symptomatic simple renal cysts can be treated by combination of percutaneous aspiration and sclerotherapy. A number of sclerosing agents including glucose, phenol, iophendylate, polidocanol, minocycline and pantopaque have been used in the past to prevent reformation of cyst. In this study, tetracycline HCL solution is evaluated as a sclerosant for treatment of simple renal cysts. Methods Our study treated 76 cysts in 70 patients with symptomatic renal cysts. Aspiration and sclerotherapy was performed on 56 cysts, and 20 cysts aspirated without sclerotherapy as a control group. Treatment was performed under local anesthesia and punctured under ultrasound guidances with an 18-gauge needle. Tetracycline HCL (20%) was injected into the cystic cavity according to cyst diameter. All patients were followed up with an ultrasound examination at 3 months, 6 months, and then at yearly intervals. The reduction rate was estimated by a comparison of the volume of the cyst before and after treatment. A cyst reduction of 50% or greater in diamater was considered as a successful treatment. Results The average follow-up period was 9.8 months in the sclerotherapy group and 9.9 months in the control group. The success rate was 85.7% in the sclerotherapy group. There was a significant difference in the reduction rate of tetracycline HCL sclerotherapy group and control group. No major complications were encountered.Öğe Pulmonary and cardiac involvement in Behcet disease: 3 case reports(SAGE PUBLICATIONS INC, 2007) Yakut, Zeynep Ilerisoy; Odev, KemalPulmonary and cardiac involvement in Behcet disease is rare but can cause life-threatening complications. This report presents computed tomography and magnetic resonance angiography findings in 3 patients with Behcet disease. Imaging findings were confirmed by surgery in 1 patient and by angiography in another. One patient had bilateral pulmonary artery aneurysms, 1 of which had already ruptured and had thrombosed. The other had unilateral pulmonary artery aneurysm and thrombosis accompanied with intracardiac thrombus formation. The third patient had unilateral pulmonary artery aneurysm, thrombus, and coronary artery aneurysm. As in our case, there have been rare reports of coronary artery disease and intracardiac thrombus formation associated with pulmonary vascular involvement. Noninvasive imaging modalities minimize any risk of endothelial damage and can be an alternative to angiography in assessment of pulmonary and cardiac involvement in Behcet disease.Öğe Radiologic findings of a traumatic urethral diverticulum with stones in an infertile male patient(TURKISH SOC RADIOLOGY, 2011) Ozbek, Orhan; Piskin, Mesut; Koc, Osman; Kadiyoran, Cengiz; Ozbek, Seda; Odev, KemalUrethral diverticulum is rarely encountered in male patients. Although postmicturition dribble, pain and infection are usually present, infertility is rarely reported in urethral diverticulum. We present a case with urethral diverticulum associated with infertility, which was diagnosed radiologically.
