A 20 year old patient referred to our clinic with complaints of secondary amenorrhea and pain. In transvaginal ultrasonography, an embryo was observed with no cardiac activity at right adnexial area. In the laparoscopy, it was seemed like bicornuate uterus.In hysteroscopy, normal left cornu, where gestational sac was not present,was entered. For this reason, unruptured ectopic pregnancy was considered in right rudimentary horn. By laparoscopy, linear incision was carried out, pregnancy material was evacuated and incision repaired primarily. Two months later, it was observed that rudimentery horn was not communicated with uterine cavity by histerosalpingography. Then, metroplasty with laparatomy was carried out. Six months later patient had had a pregnancy and delivered by cesarean section while the fetus was at the 37th gestational week. If rudimentary horn has adequate size and active endometrial tissue, metroplasty operation could be performed instead of horn excision in selected patients.
