Background: Bleeding angiomyolipomas in pregnancy are rare but may be devastating and potentially fatal. In previous cases, most of these lesions have been managed with urgent nephrectomy or embolization. Only one other case report describes treating these lesions through conservative management and vaginal delivery.
Case: A 32-year-old woman with known bilateral angiomyolipomas presented at 39 weeks of gestation with acute onset left flank pain. The ultrasound result was consistent with a bleeding angiomyolipoma. The patient was otherwise hemodynamically stable and was managed safely in a conservative outpatient approach that consisted of close clinic follow-up, serial hemoglobins, ultrasound studies, and vaginal delivery.
Conclusion: Bleeding angiomyolipomas in pregnancy were managed successfully through conservative management and vaginal delivery.
