[A 36 weeks heterotopic pregnancy discovered incidentally at the Regional University Hospital of Ouahigouya].

Heterotopic pregnancy is a rare entity, its development up to term is exceptional. We report a case of heterotopic pregnancy of fortuitous discovery during a caesarean section performed in a 26-year-old female patient received for abdomino-pelvic pain on suspected twin pregnancy of 33 SA. No obstetric ultrasound had been performed before admission. Two ultrasound ultrasounds have objectified an intrauterine twin pregnancy with hydramnios. A caesarean section at 36 weeks indicated for twin pregnancy with hydramnios and severe anemia was performed during which we discovered an intrauterine pregnancy and an abdominal pregnancy with insertion of the placenta at the level of the broad left ligament with adhesion on the left annex, Omentum and small handles. Newborns did not require any special care outside the classical essential care. The first intrauterine had a weight of 2650 g and the second abdominal of 2000 g. The postoperative sequences were simple.
