Tuberous sclerosis complex (TSC) is an inheritable disorder characterized by the formation of benign yet disorganized tumors in multiple organ systems. Germline mutations in the (hamartin) or more frequently (tuberin) genes are causative for TSC. The malignant manifestations of TSC, pulmonary lymphangioleiomyomatosis (LAM) and renal angiomyolipoma (AML), may also occur as independent sporadic perivascular epithelial cell tumor (PEComa) characterized by somatic mutations.

Background: Birt-Hogg-Dubé syndrome (BHDS) is a rare autosomal dominant genodermatosis characterized by benign growth of the hair follicles, the presence of pulmonary cysts, spontaneous pneumothorax, and bilateral renal tumors that are usually hybrid oncocytic or multifocal chromophobe renal cell carcinoma. The diagnosis is confirmed by the presence of a pathogenic variant in the tumor suppressor folliculin (FLCN) gene mapped at 17p11.2.

Angiomyolipomas (AMLs) are barely benign mesenchymal tumors that usually occur in the kidneys and may be associated with tuberous sclerosis complex (TSC). Extrarenal AMLs are markedly rare and infrequently observed in the duodenum. In the present case report, a 22-year-old female patient with duodenal AMLs presenting multiple systemic vascular malformations and aneurysms is described.

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.
