Background: Müllerian duct anomalies (MDAs) occur with an incidence estimated to be 4.3%. A unicornuate uterus with orwithout a rudimentary horn; is a type of mullerian duct abnormality with a frequency of 0.4%. Rudimentary horn pregnancies are rare obstetriccomplication and may cause difficulty in diagnosis and subsequent management. Objective: To alert about Mullerian duct abnormalitiesespecially unicornuate uterus with or without rudimentary horn. Design: Case series. Setting: Study was conducted in the department ofGynecology and obstetrics unit1, Allied Hospital Faisalabad. Duration of study: Cases detected during September 2006-0ctober 2011.Subjects and methods: All admitted cases of MDA whether obstetric or gynecological were included. We calculated cases of unicornuateUterus with or without rudimentary horn, also included cases of rudimentary horn pregnancy with or without rupture. Results: There were120cases of MDA out of which 8 (6.6%) were of unicornuate uterus. Out of 8 unicornuate uteri, 7/8 (87.5%) were with rudimentary horn and1/8(12.5%) without rudimentary horn. Left rudimentary horn in 4/8 patient (50%), right in 3/8 (37.5%) without horn1/8 (12.5%).Out of 7 rudimentaryhorn 1/7 gynecologic and 6/7 were obstetric, 5/7 (71.42%) ruptured in second trimester, and1/7 (14.28%) term pregnancy. In 1/7 (14.28%) hornnot removed because tubal ligation was done. Unilateral renal agenesis was present in 3/8 patient (37.5 %). Ovaries were preserved in 3/7patients (66%). Conclusions: There must be high index of suspicion for Mullerian duct abnormalities especially rudimentary horn for achievinggood success in diagnosis and management.
