Primary twin omental pregnancy: report of a rare case and literature review

Objective: To report a very rare case of a primary twin omental pregnancy. Design: Case report. Setting: The emergency department of a university teaching hospital. Patient(s): A 36-year-old woman. Intervention(s): Partial omentectomy by laparotomy. Main Outcome Measure(s): Laparotomy successfully performed in the case of a twin omental pregnancy. Result(s): A 36-year-old woman presented with intense abdominal pain of 3 days' duration, hypotensive, with distended abdomen and signs of peritoneal irritation, and no transvaginal bleeding or evidence of topic pregnancy. Laparotomy showed normal internal genital organs and the presence of a large hemoperitoneum with a twin omental pregnancy. Partial omentectomy was performed. The patient progressed well postoperatively, and subsequent beta-hCG titer was negative. Conclusion(s): Primary omental twin pregnancy is extremely rare, and when associated with acute abdomen and large hemoperitoneum, laparotomy is required for treatment.
