title: Hemangiopericytoma of the kidney: a case with preoperative ethanol embolization.
abstract: We report a case of a giant renal hemangiopericytoma that was embolized preoperatively with ethanol. Ultrasound and computerized tomography showed multiple smooth-walled cysts within the tumor. The tumor itself was hypervascular and a vascular pattern specific for hemangiopericytoma was noted upon reinterpretation of the angiograms. The diagnostic and therapeutic aspects are discussed, and the literature is reviewed.
