Background Cesarean scar rupture of a gravid uterus in early gestation is rare.

Case A 38-year-old woman, gravida 4, para 2-0-1-1, presented at 13 weeks' gestation with cramping and spotting. She had a history of two cesareans. Ultrasound and magnetic resonance imaging indicated probable uterine dehiscence and a viable extrauterine pregnancy. After embolization of the uterine arteries with subsequent fetal death, the subject had a hysterectomy. Intraoperatively, she had complete rupture of the lower uterine segment, but the pregnancy was enclosed within scar tissue between the uterus and bladder. Placenta percreta was found by histologic examination.

Conclusion Women with histories of cesareans might be at risk of early uterine rupture.

Extrauterine pregnancy might result from early rupture of a cesarean scar.
