Treatment for ruptured renal angiomyolipoma in pregnancy requires immediate and appropriate decision-making based on the condition of the mother and fetus, and gestational age. A 37-year-old woman at 25weeks of pregnancy presented with severe right flank pain. Computed tomography showed a ruptured right renal angiomyolipoma (8cm in diameter). The maternal and fetal conditions were stable. Transcatheter arterial embolization was carried out electively 4days after the rupture. Minimization of radiation exposure to the fetus was achieved by X-ray shielding for the fetus, low-dose-rate fluoroscopy, minimal angiography imaging and a color Doppler ultrasonography-guided procedure. Although threatened premature labor occurred because of post-embolization syndrome, the pregnancy was continued until cesarean section at 37weeks of pregnancy.
