We report a case of a 56-year-old male under investigation for large lytic lesion at clivus. After lesion resection, patient was referred to abdominal computed tomography scan for metastasis screening. The lesion was posteriorly characterized as chondroid chordoma at histopathology examination. On non-enhanced computed tomography, multiple hypottenuating nodules of different sizes were seen; the largest nodule had 3.2cm. On post-contrast phases lesions had similar enhancement to adjacent liver parenchyma. However, no significant mass effect or invasiveness were seen, once vascular […]

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 […]
