Hemangioma of the pericardium: a case report.

A 52-year-old male presented with dyspnoea on exertion. He was found to have a clinically normal cardiac status and a mass lesion in the anterior mediastinum, probably arising from the pericardium near the right atrium, as shown by both echocardiography and a computerized tomographic scan of the chest. He was successfully operated. The histopathology of the mass revealed it to be a hemangioma of the pericardium. This is one of the rare tumors of the pericardium and only a few cases have been reported in the literature.
