[Management of hemorrhage secondary to renal angiomyolipoma]

A case of bilateral angiomyolipoma which was complicated with retroperitoneal massive hemorrhage and in which right-nephrectomy was performed is reported. Eight years ago, this patient had tuberous sclerosis and underwent open renal biopsy with which the diagnosis was confirmed. This patient was admitted for shock caused by the retroperitoneal massive hemorrhage from tumor. For about 30 days, the patient was treated conservatively, such as blood transfusion and hyperalimentation, but retroperitoneal massive hemorrhage reoccurred and the patient underwent right-nephrectomy. The treatment for bilateral angiomyolipoma complicated with retroperitoneal massive hemorrhage is discussed.
