Abstract:
Renal angiomyolipoma is a benign tumor of the kidney, originating from perivascular epithelioid cells. Normally asymptomatic, symptoms that can occur are flank pain due to strong growth or spontaneous rupture with retroperitoneal hemorrhage and hypovolemic shock. The risk of rupture is higher during pregnancy and also growth can be enhanced, probably hormone mediated. We report a case of a ruptured renal angiomyolipoma during childbirth in a woman who presented with hypovolemic shock as a result of retroperitoneal hemorrhage. Emergency endovascular treatment was successful with sparing most of the affected kidney as demonstrated by angiography imaging and follow-up computed tomographic scan.
