A Rare Presentation of Viable Intrauterine Pregnancy with Coexisting Complete Molar Pregnancy in a Uterus Didelphys

Complete hydatidiform mole with co-existing live intrauterine fetus is an extremely rare event. Mullerian anomalies such as uterus didelphys are uncommon variants of normal anatomy. Uterus didelphys is one of the congenital uterine anomalies due to defective medial fusion of mullerian ducts. This anomaly is known to have poor reproductive outcome. It poses a great challenge for the obstetrician to decide for or against the continuation of such a pregnancy. Although successful outcomes in the form of live births have been reported, continuation of pregnancy till term is usually uncommon. We report a case of 23 year old female with USG report revealing a uterus didelphys with live intrauterine pregnancy in the right horn of 7.6 weeks with complete molar pregnancy in the left horn.
