title: Spontaneous rupture of a renal angiomyolipoma at 25 weeks of pregnancy treated with transarterial embolization: A case report and review of the literature.
abstract: 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 25 weeks of pregnancy presented with severe right flank pain. Computed tomography showed a ruptured right renal angiomyolipoma (8 cm in diameter). The maternal and fetal conditions were stable. Transcatheter arterial embolization was carried out electively 4 days 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 37 weeks of pregnancy.
