Secondary missed abdominal pregnancy due to iatrogenic uterine perforation: a case report.

Abdominal pregnancy is extremely rare and can result from the reimplantation of an intrauterine pregnancy after spontaneous uterine rupture. In this report, we present the case of a secondary missed abdominal pregnancy resulting from iatrogenic uterine perforation during dilatation and curettage in an early intrauterine pregnancy and subsequently misdiagnosed as intrauterine trophoblastic disease. Transvaginal ultrasound missed the diagnosis, which was finally confirmed by computed tomography. We discuss the particulars of the case along with a review of the relevant literature.
