title: Cavernous hemangioma of the kidney.
abstract: Three patients with cavernous hemangiomas of the kidney all presented with hematuria. In each there was found a poorly defined renal medullary mass with displacement of the calyces and renal vessels and paradoxical hypovascularity of the mass. This rare, benign tumor of the kidney should be considered in the presence of this characteristic clinical picture.
