Uterus didelphys is one of the developmental malformations of the mullerian ducts because of non-fusion in the midline resulting in two separate uteri. Simultaneous twin gestation with each fetus in a separate horn of uterus didelphys is an extremely rare entity. Herein, we report a case with spontaneous gestations in each uterine cavity in which the course of pregnancy of the right horn was complicated by preterm labor.
