Ruptured Left Cornual Ectopic Pregnancy: A Case Report.

Cornual ectopic pregnancies are rare with a mortality rate that is significantly higher than that of other ectopic pregnancy types. Due to the cornual region's location on the fallopian tube, rupture of a cornual gestation may lead to massive maternal hemorrhage resulting in hypovolemia and shock. Here, we report a 39-year-old female who presented to Hospital Corporation of America (HCA) Florida Healthcare's emergency department (ED) in a state of hypovolemic shock. She was six weeks pregnant based on an unknown and unsure last menstrual cycle. The diagnosis of a ruptured ectopic pregnancy was suspected based on a positive urine pregnancy test and a pelvic ultrasound that revealed an empty uterus and a copious amount of free fluid within the abdomen. Significant hematoperitoneum and hemodynamic instability required emergent exploratory laparotomy with findings of a ruptured left cornual ectopic pregnancy. A left cornual resection and repair was done with an uneventful postoperative period. With cornual ectopic pregnancies being a rare entity, our case emphasizes the importance of early detection and management to help prevent fatal complications.
