title: Primary omental ectopic pregnancy.
abstract: Omental ectopic pregnancy is a rare form of ectopic pregnancy. Presented here is a case primary omental ectopic pregnancy according to Studdiford's criteria. This patient presented with epigastric pain and anemia without vaginal bleeding, lower abdominal or pelvic pain. Pregnancy status was confirmed after admission. Transvaginal ultrasound examination revealed intrauterine contraceptive device in situ and a large amount of free peritoneal fluid, but no intrauterine sac or adnexal mass. Laparoscopy was performed but pelvic pathology did not account for the 2500 mL of haemoperitoneum. Laparotomy was carried out and partial omentectomy was performed.
