Management of bleeding renal angiomyolipomas by transcatheter embolization following CT diagnosis

Abstract
Renal angiomyolipomas are commonly associated with spontaneous hemorrhage which can be life-threatening and may require radical nephrectomy for control of hemorrhage. Transcatheter embolization was used in 2 cases of spontaneously bleeding angiomyolipomas; permanent control was achieved in 1 case and temporary control in the other. This more conservative approach was made possible by our ability to diagnose these benign renal tumors confidently using computed tomography.
