Unicornuate Uterus and Rudimentary Horn: An Unusual Cause of Recurrent Fetal Malpresentation Identified During a Scheduled Cesarean Delivery

This case report presents a unique clinical scenario involving a 32-year-old woman with a unicornuate uterus and a rudimentary horn, leading to recurrent fetal malpresentation. The patient, gravida 3, para 1, presented at 36 weeks of gestational age with contractions and vaginal bleeding. Clinical evaluation revealed a breech presentation and nonreassuring fetal heart tracings. An emergency cesarean section was performed, during which a unicornuate uterus with a rudimentary horn was identified and fused to the main uterine cavity on the left posterior aspect. The rudimentary horn bore a functional left tube and ovary. The surgical procedure was successful, resulting in the delivery of a healthy baby girl. This case underscores the importance of meticulous preoperative assessment, multidisciplinary collaboration, and informed consent in managing complex uterine anomalies to ensure optimal maternal and fetal outcomes.
