Quadruplet heterotopic pregnancy; ectopic managed successfully with laparotomy with subsequent viable intrauterine pregnancy: A case report.

Heterotopic pregnancy is characterized by a concurrent intrauterine and ectopic pregnancy. It can occur after natural conception, however, it is more common with assisted reproductive techniques , when over one embryo is transferred. Quadruplet heterotopic pregnancy is an exceedingly rare subset. Our case describes a woman who presented to the emergency room with amenorrhea for 9 weeks and lower abdominal pain for 3 days. Transvaginal ultrasound revealed three alive intrauterine fetuses and one left tubal ectopic pregnancy (Quadruplet heterotopic pregnancy). Patient benefited from emergent laparotomy with favorable outcome both in the short term and in the long term. In a patient with a history of assisted reproductive techniques, a high index of suspicion is warranted towards extra-uterine pregnancy. Sonologists should precisely look for adnexal mass. The presence of peritoneal free-fluid requires further investigation. The prognosis of intrauterine fetuses is good, provided the ectopic pregnancy is managed timely and in an effective manner.
