Solitary malignant mesothelioma of the small intestine: radiological appearances.

Malignant peritoneal mesothelioma is virtually unknown to feature as a solitary lesion. A patient presented with abdominal pain, weight loss, and melena and underwent enteroclysis, computed tomography, and superior mesenteric arteriography. Sharp angulation, narrowing, and mucosal destruction in a jejunal segment, caused by an encapsulating infiltrative mesenteric mass, were shown.

Primary hydatid disease of the pancreas.

A case of primary hydatid disease of the pancreas is presented in a patient operated on for an adrenal mass. Computed tomographic findings, such as rounded cystic lesion with curvilinear calcification, may allow the diagnosis to be made in the appropriate clinical setting. The diagnosis was confirmed at surgery.
