    Supposed to be rare cause of intestinal obstruction; abdominal cocoon: report of two cases
    (2013-05-01T00:00:00Z) Serter, Asli; KOCAKOÇ, ERCAN; Cipe, Gokhan; KOCAKOÇ, ERCAN
    Abdominal cocoon, or sclerosing encapsulating peritonitis, is supposed to be rare cause of intestinal obstruction. It is characterized by totally or partially encasement of small bowel with a thick, fibrotic, cocoon-like membrane. We think this entity is not rare as previously thought. We reported two case-s clinical and imaging findings which diagnosed abdominal cocoon by surgery to increase awareness of this diagnosis. (C) 2013 Elsevier Inc. All rights reserved.

    The role of apparent diffusion coefficient values in differentiation between adrenal masses
    (2014-03-01T00:00:00Z) Cicekci, Mehtap; ONUR, MEHMET RUHİ; Aydin, Ayse Murat; Gul, Yeliz; ÖZKAN, YUSUF; AKPOLAT, NUSRET; KOCAKOÇ, ERCAN; KOCAKOÇ, ERCAN
    The aim of this study was to evaluate the utility of apparent diffusion coefficient (ADC) values in differentiation between solid adrenal masses. The ADC values of 73 adrenal lesions (54 benign, 19 malignant) in 69 patients were measured at b 100, 600 and 1000 gradients on diffusion-weighted magnetic resonance imaging (DW-MRI). No statistically significant difference was found between ADC values of benign and malignant adrenal masses, nonadenomatous benign adrenal masses and malignant adrenal masses, adrenal adenomas and nonadenomatous lesions, adenomas and metastases, adenomas and pheochromocytomas, metastases and pheochromocytomas. ADC values are not helpful in the differentiation between solid adrenal masses. (C) 2014 Elsevier Inc. All rights reserved.

    Utility of ADC measurement on diffusion-weighted MRI in differentiation of prostate cancer, normal prostate and prostatitis
    (2013-08-01T00:00:00Z) Esen, Meltem; ONUR, MEHMET RUHİ; AKPOLAT, NUSRET; ORHAN, İRFAN; KOCAKOÇ, ERCAN; KOCAKOÇ, ERCAN
    To determine the utility of apparent diffusion coefficient (ADC) values in differentiation of prostate cancer from normal prostate parenchyma and prostatitis we obtained ADC values of 50 patients at b 100, 600 and 1,000 s/mm(2) diffusion gradients. The ADC values of prostate cancer group were significantly lower than normal prostate and prostatitis group at b 600 and 1,000 s/mm(2) gradients. The ADC values at high diffusion gradients may be used in differentiation prostate cancer from normal prostate and prostatitis.

    Doppler ultrasonography and magnetic resonance imaging findings of testicular adrenal rest tissue in a patient with 11 beta hydroxylase deficiency. Case report
    (2014-12-01T00:00:00Z) Ahmad, Issam Cheikh; YILMAZ, Temel Fatih; KOCAKOÇ, ERCAN; YILMAZ, TEMEL FATİH; KOCAKOÇ, ERCAN
    Benign intratesticular lesions are rare; thus, radiological diagnosis is important to avoid unnecessary surgical intervention. Testicular adrenal rest tumors (TART) are the nodular testicular lesions deriving from the adrenal remnant tissue reported in patients with congenital adrenal hyperplasia. We present ultrasonographic (US) and magnetic resonance imaging (MRI) findings of intratesticular adrenal rests in a 16-year-old patient with 11 beta hydroxylase deficiency. Scrotal ultrasonography demonstrated bilateral heterogenous hypoechoic lesions located around mediastinum testis and highly vascularized on powerDoppler US. On MRI the lesions were hyperintense on T1-weighted and hypointense on T2-weighted images and enhanced brightly on post-contrast images.

    Evaluation of left renal vein entrapment using multidetector computed tomography
    (2013-03-01T00:00:00Z) POYRAZ, AHMET KÜRŞAD; FIRDOLAŞ, FATİH; ONUR, MEHMET RUHİ; KOCAKOÇ, ERCAN; KOCAKOÇ, ERCAN
    Background: Nutcracker syndrome, also called left renal vein entrapment syndrome, is a cause of non-glomerular hematuria with difficulties in diagnosis. Multidetector computed tomography (MDCT) is a powerful tool to prevent unnecessary diagnostic procedures.

    Cystic abdominal masses in children: a pictorial essay
    (2013-01-01T00:00:00Z) ONUR, MEHMET RUHİ; BAKAL, ÜNAL; KOCAKOÇ, ERCAN; TARTAR, TUGAY; KAZEZ, AHMET; KOCAKOÇ, ERCAN
    Cystic abdominal masses in children are not an infrequently encountered condition of childhood. These lesions usually present with large size and mimick each other with similar presenting symptoms. Imaging examinations have an important role to determine the type of the cystic abdominal masses, which is crucial for management of patients and presurgical planning. In this pictorial essay, we summarized the imaging features of common cystic abdominal masses of children, including cystic lesions arising from liver, biliary ducts, kidney, pancreas, bowel, ovary, mesentery, and miscellaneous tissues.
