We report the computed tomographic and angiographic findings in the case of a recently obtained successful clinical outcome after embolization of the hepatic artery in the case of a snakebite causing hemoperitoneum associated with hepatic necrosis and rupture with active bleeding.
Pericardial fat necrosis is an infrequent cause of acute chest pain and this can mimic acute myocardial infarction and acute pericarditis. We describe here a patient with the magnetic resonance imaging (MRI) findings of pericardial fat necrosis and this was correlated with the computed tomography (CT) findings. The MRI findings may be helpful for(More)
We report a case of unusual bronchopulmonary foregut malformation composed of a mediastinal bronchogenic cyst with sequestrated lung tissue and communicating tubular esophageal duplication associated with complete pericardial defect. A 18-yr. old man, who had suffered from dry cough and mild dyspnea, was admitted because of an incidentally detected chest(More)
Many hospitals experience one or more retained surgical instrument events with risk of patient morbidity and medicolegal problems. Identification of retained surgical instrument is important. The radiologists should be familiar with imaging finding of retained surgical instrument. In a 62-year-old female with a retained plastic tube, localized peritoneal(More)
PURPOSE The aim of this study was to define the capsules of synchronous multicentric small hepatocellular carcinomas (HCCs) with use of high-frequency intraoperative ultrasonography (IOUS). METHODS Among the 131 consecutive patients undergoing hepatic resection and high-frequency IOUS for HCC, 16 synchronous multicentric small HCCs in 13 patients were(More)
Nerve compression syndromes commonly involve the nerves in the upper extremity. High-resolution ultrasonography (US) can satisfactorily assess these nerves and may detect the morphological changes of the nerves. US can also reveal the causes of nerve compression when structural abnormalities or space-occupying lesions are present. The most common US finding(More)
OBJECTIVE We observed patients in whom the fluid collection in the right lateral portion of the superior aortic recess on computed tomography (CT) scans mimicked a right anterior mediastinal mass on chest PA radiographs. The purpose of this study was to assess chest PA and CT features of these patients. MATERIALS AND METHODS All chest PA radiographs and(More)
