title: Bleeding renal angiomyolipoma presenting as duodenal obstruction.
abstract: We report a case of a 60-year-old woman who had a delayed presentation of duodenal obstruction as a result of a bleeding right renal angiomyolipoma (AML) with retroperitoneal hematoma. Her duodenal obstruction did not improve upon conservative management, and a computed tomography (CT)-guided drainage of the retroperitoneal hematoma was subsequently performed. Post-intervention, CT scan confirmed hematoma resolution, and she was able to resume normal diet afterwards. We present this first reported case of a bleeding renal AML with retroperitoneal hematoma causing duodenal obstruction and discuss on the management of such condition.
