[Retroperitoneal hemorrhage as a complication of renal angiomyolipoma].
Renal angiomyolipoma (AML) is an uncommon, benign neoplasm of a hamartomatous origin that presents as multiple bilateral lesions occasionally associated with tuberous sclerosis, or as a single unilateral lesion. They are generally asymptomatic, and can manifest the following clinical triad: abdominal pain, palpable mass and hematuria. Retroperitoneal hemorrhage is a rare complication (9%). We report 3 cases of spontaneous rupture of renal AML with massive hemorrhage; two of these cases were associated with tuberous sclerosis. This complication was the presenting feature of renal AML in two cases. Radiologic diagnosis and management of this tumor type are highlighted.
