Endovascular Treatment of Renal Angiomyolipoma Rupture - Case Report

Abstract

Renal angiomyolipoma is a rare type of benign tumor composed of blood vessels, adipocytes and smooth muscle fibers. It is commonly associated with patients with tuberous sclerosis. It presents asymptomatically and is usually diagnosed incidentally. In cases of spontaneous rupture, it may manifest through Wunderlich's syndrome, and may present pararenal retroperitoneal hemorrhage. This article presents the case of an 18-year-old patient who was initially transferred to Hospital Risoleta Tolentino Neves with suspected acute appendicitis, but was diagnosed with probable hemorrhagic angiomyolipoma on the right by computed tomography of the abdomen and pelvis. Embolization of interlobar branches of the upper pole of the right kidney was performed with resolution of the condition, without the need for a surgical approach.
