title: Giant renal angiomyolipoma with fatal hemorrhage due to a large pseudoaneurysm.
abstract: We report a case of giant renal angiomyolipoma (AML) with a large pseudoaneurysm causing fatal hemorrhage. A 60-year-old woman presented with right-sided abdominal pain. Sonographic examination revealed a large hyperechoic renal mass. CT examination of the abdomen revealed a 15-cm AML of the right kidney with a large hemorrhagic area within it. Subsequent color Doppler examination revealed a 2.9-cm pseudoaneurysm arising from the upper segmental branch of the right renal artery. The patient, who was about to undergo transcatheter embolization of the pseudoaneurysm, died from cardio-respiratory arrest. The autopsy findings confirmed a large right renal AML containing a thrombosed pseudoaneurysm and a large perinephric hematoma.
