First-trimester diagnosed cervico-isthmic pregnancy resulting in term delivery.

A 30-year-old multiparous woman at 5.5 weeks' gestation was diagnosed by ultrasound to have a cervical pregnancy. She refused termination because of religious beliefs. After expectant management until 38 weeks' gestation, she delivered a viable infant by cesarean, followed by immediate hysterectomy. Pathologic examination verified cervico-isthmic implantation as well as placenta percreta.
