ABSTRACT Objectives: To evaluate the use of magnetic resonance imaging in patients with β-thalassemia and to compare T2* magnetic resonance imaging results with serum ferritin levels and the redox active fraction of labile plasma iron. Methods: We have retrospectively evaluated 115 chronically transfused patients (65 women). We tested serum ferritin with chemiluminescence, fraction of labile plasma iron by cellular fluorescence and used T2* MRI to assess iron content in the heart, liver, and pancreas. Hepatic iron concentration was determined in […]

ABSTRACTPericardial cysts account for 12-18% of all mediastinal masses. They are usually asymptomatic and incidentally detected. However, when large, they can cause symptoms. Most pericardial cysts are located in the right cardiophrenic angle, but they can be anywhere in the mediastinum. We reported a pleuropericardial cyst torsion after physical stress, a very rare complication of this condition. The diagnosis was made by computed tomography and confirmed by video-assisted thoracoscopy.

ABSTRACTAdnexial torsion is an unusual event, but a major cause of abdominal pain in women. It is often associated with ovarian tumor or cyst, but can occur in normal ovaries, especially in children. The twisting of adnexial structures may involve the ovary or tube, but frequently affects both. In most cases, it is unilateral, with slight predilection for the right side. In imaging findings, increased ovarian volume and adnexial masses are observed, with reduced or absent vascularization. In cases of […]
