Ruptured Ectopic Pregnancy in a Non-communicating Rudimentary Horn at 18 Weeks of Gestation.

This case highlights the critical role of early radiological screening by ultrasound in identifying uterine anomalies. In this report, we discuss a 39-year-old pregnant woman, gravida 4 para 3, and her fetus at gestational age 18 weeks. The patient was referred to the Obstetrics and Gynecology Emergency Department at Qatif Central Hospital, Saudi Arabia, from a private hospital due to an ultrasound study indicating a possible ectopic pregnancy with an abdominal fetal location. The multidisciplinary team of obstetrics and gynecology and radiology conducted additional radiological examinations, including magnetic resonance imaging (MRI), leading to a diagnosis of suspected ruptured non-communicating rudimentary horn ectopic pregnancy. Subsequently, an emergency laparotomy was successfully performed, resulting in the removal of the rudimentary horn and the termination of the ectopic pregnancy.
