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.


METHODS
Case report.


METHODS
The emergency department of a university teaching hospital.


METHODS
A 36-year-old woman.


METHODS
Partial omentectomy by laparotomy.


METHODS
Laparotomy successfully performed in the case of a twin omental pregnancy.


RESULTS
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.


CONCLUSIONS
Primary omental twin pregnancy is extremely rare, and when associated with acute abdomen and large hemoperitoneum, laparotomy is required for treatment.
