Cavernous hemangioma of the renal hilum presenting as an avascularized solid mass.

Hemangiomas are slowly growing benign vascular tumours which rarely involve the kidney. They usually occur in the mucosa or subepithelial tissue of the pelvis, in the pyramid of the kidney and in the cortex. We report a case of cavernous hemangioma presenting as a solid, paradoxically avascular mass of the right renal hilum. Copyright 2003 S. Karger AG, Basel
