Behçet's disease is a rare form of vasculitis of obscure etiology. Any large or small artery, vein, or organ may be involved in an unpredictable combination. Intrathoracic manifestations of Behçet's disease consist mainly of thromboembolism of the superior vena cava and/or other mediastinal veins; aneurysms of the aorta and pulmonary arteries; pulmonary(More)
Percutaneous aspiration of purely cystic liver lesions was performed in 15 patients aged 11-56 years. After aspiration under guidance with computed tomography (CT) in 12 patients, a membrane that is diagnostic for hydatid disease was visible in the lumen of the cyst on CT scans. Hypertonic saline was injected in the cystic cavities of these patients as a(More)
Replacement lipomatosis (RPL) is seen in patients in whom renal parenchyma is destroyed due to chronic calculous disease and inflammation. The triggering mechanism for xanthogranulomatous pyelonephritis (XGP) is also the same. We report a case in which RPL and XGP coexist in the same kidney. To our knowledge, this coexistence has not been previously(More)
Twenty-eight patients with colon carcinoma (excluding the recto-sigmoid region) underwent preoperative staging with computed tomography (CT). The CT had a sensitivity and a specificity of 60 and 67% for detection of extramural invasion, 75% sensitivity and specificity for lymph node metastases and a sensitivity of 87% and specificity of 95% for liver(More)
CT findings in pulmonary Gaucher's disease have not been previously reported. Chest radiograph of a patient with pulmonary involvement in type I Gaucher's disease proven by biopsy showed linear and reticulo-nodular opacities. High-resolution CT demonstrated thickening of the interlobular septa and between four and six small nodules within secondary lobules,(More)
We reviewed the CT findings of 13 patients with histologically proved alveolar echinococcosis of the liver. Seven of these patients had hilar involvement, which caused dilatation of intrahepatic bile ducts and invasion of the portal vein or portal branches. In two of these patients we found marked atrophy of the right lobe and in one patient marked atrophy(More)
, The European Vertebral Osteoporosis Study (EVOS) is a multinational survey aimed to determine the prevalence of vertebral I osteoporosis (VOP) across different populations in Europe and to identify the proportion of the vamatmn in fracture occurrence explained by risk factors. We report the data concerning the individuals who were selected in Istanbul(More)
A method is described for measuring the thickness of the cranial bones in x-ray pictures of the skull, which in a reliable way can only be done in the frontal and the parietal bones. From the results, representative and comparable values have been obtained consisting of the mean and maximum thickness of the bones and of the mean deviation of the thickness(More)
BACKGROUND Optimal duration of adjuvant trastuzumab in early breast cancer is an unresolved issue. In this observational study, we compared the outcome of 9 weeks and 1 year adjuvant trastuzumab in early breast cancer patients in Turkey. METHODS Records of 680 patients with HER2-positive early breast cancer who received adjuvant trastuzumab plus(More)
