Delayed diagnosis and management of late second trimester intra-abdominal pregnancy

Abstract

Abdominal pregnancy resulting in lithopedion is a rare condition constituting only 0.0054% of all pregnancies. This is a case of a 48-year-old Gravida 6 Para 3 (3-0-2-2) who consulted at the emergency room for an ultrasound finding of abdominal pregnancy. The patient had previous imaging done which showed a live intrauterine pregnancy until her fourth ultrasound, showing fetal death in utero. After several months without passage of the products of conception, a repeat ultrasound showed an abdominal pregnancy. Diagnosis of abdominal pregnancies may be difficult, thus it is important to utilize other imaging modalities to confirm the diagnosis. The mainstay for treatment for abdominal pregnancies is laparotomy. However, due to the possible severe hemorrhage that may arise intraoperatively, preoperative and postoperative arterial embolization of feeding vessels may be performed, as was done in the case discussed.
