Pulmonary vein varix is a rare benign abnormality, either congenital or acquired, usually presented without symptoms. It is most frequently discovered by chance on a chest radiograph, whereas computed tomography defines the special characteristics of the lesion. Angiography is considered the method of choice for final diagnosis. The authors present the first case of a patient with pulmonary vein varix accompanied by interatrial communication.

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. The diagnosis of a malignant peritoneal mesothelioma, localized to the small intestine, was made at histology.
