Conservative management of a retroperitoneal hemorrhage following a ruptured renal angiomyolipoma in pregnancy.

Retroperitoneal hemorrhage following ruptured renal angiomyolipoma is usually managed surgically or by embolization. But when the same episode occurs in pregnancy, surgery which predisposes to preterm delivery and its subsequent sequelae, the unknown influences of radiation exposure on the fetus makes the management of such cases very challenging. A 21-year-old woman was seen in the emergency unit at the 25th week of her pregnancy with complaints of sudden onset left flank pain radiating to the back, nausea and hematuria.
