Pregnancy in the rudimentary horn of a unicornuate uterus is a rare obstetric occurence. Rarer still is the continuation of such a pregnancy resulting in a term live birth with a healthy mother and child. Presented here is a case of a 28 year old primigravid who was referred at 40 weeks age of gestation and admitted for cesarean section for malpresentation. Intraoperatively, a transverse incision was done on the lower portion of the gravid rudimentary horn to deliver the baby followed thereafter by its removal by doing a hemi-hysterectomy. The patient gave birth to a healthy baby girl weighing 2100g with an APGAR score of 8-9 and a pediatric aging of 38 weeks. Discussed herein is the possible mechanism for fertilization in rudimentary horn pregnancies, its possible complications and its management.
