A triplet's ectopic pregnancy in a non-communicating rudimentary horn and spontaneous rupture.

Our aim is to feature the management of ectopic pregnancy in a non-communicating rudimentary horn. It has a remarkable life-threatening potential, being rare and difficult to be considered during differential diagnosis of acute abdomen or sudden maternal collapse in early pregnancy. Therefore, this is a report of mid-trimester triplet's ectopic pregnancy which presented with sudden repeated syncopal attacks and hemodynamic instability that necessitated emergency laparotomy to treat ruptured non-communicating rudimentary horn. The rarity of this clinical condition can lead to multiple challenges. When a diagnosis is confirmed, the intervention plans should be independently tailored based on the patient's age, obstetric history, fertility wishes, as well as, surgeon's experience. Moreover, most cases passed unnoticed till complications took place. Thus, early diagnosis of Mullerian anomalies preconceptionally or even during the initial antenatal visits is crucial step regarding the avoidance of such catastrophic maternal outcomes.
