Endovascular treatment of sporadic renal angiomyolipoma presenting with Wunderlich syndrome

Abstract

Angiomyolipomas are benign renal hamartomas with - fat, smooth muscle, and abnormal blood vessel (tortuous, dysmorphic) components. The risk of hemorrhage is related to size of the tumor, presence of aneurysm, associations with tuberous sclerosis. In this case report we review the case of a 42-year-old woman presenting with acute flank pain and decreased hemoglobin, who was diagnosed with AML with right renal artery pseudo aneurysm on CT. Subsequent coil embolization of feeding vessels and using PVA particles was successfully done. Selective embolization remains a minimally invasive, attractive option, and a nephron sparing approach.
