Conjoined twins - A case report of prenatal diagnosis of cephalothoracoomphalopagus

Conjoined twins are an exceptionally rare phenomenon caused by partial separation of an early embryo after the twelfth day of fertilization. In this article we are reporting a case of conjoined twins diagnosed in our department. During a examination in the XXI week of gestation, a 24 years old woman, with the presence of labial herpes simplex following an ultrasound examination was suspected of carrying conjoined twins. To confirm, we performed prenatal Magnetic Resonance Imaging (MRI), which proved the existence of cephalothoracoomphalopagus.
