A case of cesarean scar ectopic: a rare but important form of ectopic pregnancy

Abstract

Abstract Introduction This is a case of a 35-year-old G4P3 female with history of one prior cesarean section who presented to the emergency department with vaginal bleeding. She was found to be pregnant, and an ultrasound identified a cesarean scar ectopic pregnancy. Methods This is a case report and brief review of the literature. Conclusion Cesarean scar ectopic is a rare form of ectopic pregnancy that implants within the myometrium at the site of a prior cesarean section scar. It carries the potential for serious maternal morbidity and mortality, including complications like uterine rupture, life-threatening hemorrhage, and need for hysterectomy. All sonographers who scan patients in first-trimester pregnancy should be aware of the criteria to diagnose this entity, as cesarean scar ectopic can otherwise be confused with cervicoisthmic pregnancy or spontaneous abortion in progress.
