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 β-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.
