A mediastinal hemangioma, associated with perirenal hemangioma and congenital anomaly of the inferior vena cava.

In a 40-year-old man, a mediastinal hemangioma was discovered intially as a compression of the esophagus by upper gastrointestinal endoscopy. Furthermore, perirenal hemangioma and inferior vena cava (IVC) malformation were stimultaneously found. Hemangiomas, which occur in the mediastinal and perirenal area, are extremely uncommon and congenital IVC malformation, like the present case, has not been reported. We review the literature of these vascular abnormalities.
