Successful deliveries in a case of spontaneous pregnancy in ‘uterus bicornis unicollis’ with dicavitory twin gestation: a rare case report

Congenital anomalies of the uterus cervix and vagina are caused by alterations in development or fusion of the Mullerian ducts and are associated with multiple obstetric problems. A 32-year-old primigravida presented with spontaneous conception of dichorionic diamniotic twin with one twin in the right horn and another in the left horn of a bicornuate uterus.
