Pregnancy in rudimentary horn of unicornuate uterus is not something we see every day in our clinics, requires high suspicion to diagnose, and often increases morbidity of the patient if missed. But with prior knowledge of such cases and an alert mind, this can be detected early with a good ultrasound scan and adequate treatment can be done. We recommend laparoscopic surgical excision of the rudimentary pregnant horn for a one time proper definitive treatment of the patient.
