Laparoscopic management of a unicornuate uterus with two cavitated, non-communicating rudimentary horns

An 18 year old nulligravid woman presented with severe dysmenorrhoea secondary to stage IV (revised American Fertility Society) endometriosis, right haematosalpinx, right endometrioma, unicornuate uterus and two cavitated, noncommunicating rudimentary uterine horns. To our knowledge, this is the first reported case of a unicornuate uterus accompanied by two rudimentary horns. Operative video-laparoscopy proved a successful approach for treating this previously unreported variant of congenital Mullerian anomaly. A review of the world literature confirms the uniqueness of this case while demonstrating laparoscopy to be a viable alternative to laparotomy for management of congenital Mullerian anomalies. The case presented may help to elucidate Mullerian duct embryology further.
