Spontaneous rupture of renal angiomyolipoma: value of multidetector CT angiography for interventional therapy.

Renal angiomyolipomas have a high risk of rupture when they are large and associated with aneurysms. When renal angiomyolipomas rupture, some patients go into shock. Immediate interventional therapies to stop bleeding are required. In the present case, multidetector computed tomographic angiography provided useful information for planning the interventional therapy. Because of the information, transcatheter arterial embolization was safely performed while preserving most renal function.
