A female fetus of a dizygotic pregnancy presented with a retrovesical cystic mass at 16 weeks. Severe and recurrent fetal ascitis developed at 25 weeks. Pre-eclampsia, probably due to mirror syndrome, precipitated fetal extraction, which led to severe prematurity complications and neonatal death. Necropsy showed: cloacal anomaly, anal atresia, ambiguous genitalia and bicornuate uterus.
