Abstract No. 320 EE: Current Concepts in the Evaluation and Transcatheter Management of Symptomatic Renal Angiomyolipomas

Abstract

Renal angiomyolipoma, a benign hamartoma composed of varying amounts of vascular, smooth muscle and fat elements, occurs in either solitary or multifocal fashion. If the abnormal vascular elements predominate or if the tumor is of significant size, patients may become clinically symptomatic and thus require intervention. Symptoms may include hematuria, flank pain, fever and hypotension. Causes for these symptoms relate to tumor size, spontaneous retroperitoneal hemorrhage, erosion into the renal collecting system and renal infarction.
