Amniotic Sac Herniation Through a Prior Cornual Scar in The Third Trimester.

Introduction  Uterine rupture occurs in less than 0.1% of pregnancies. This complication can be detrimental to mother and fetus if not detected and managed in a timely manner. We report an unusual presentation of uterine scar rupture that was diagnosed on ultrasound in a completely stable patient with reassuring fetal status. Case Report  A 24-year-old Gravida 5, Para 3 with history of cornual resection for ectopic pregnancy and two previous uterine ruptures presented at 30 weeks' gestation with worsening abdominal pain. Ultrasound identified herniation of the amniotic sac with fetal parts. The patient underwent cesarean delivery and cornual defect repair. Conclusion  Close observation and early delivery remain vital to the patient's management.
