Monocephalus diprosopus, a rare form of conjoined twins, and associated congenital anomalies.
Craniofacial duplication (diprosopus) is a rare form of conjoined twins. A case of monocephalus diprosopus with anencephaly, cervicothoracolumbar rachischisis, and duplication of the respiratory tract and upper gastrointestinal tract is reported. The cardiovascular system remained single but the heart showed transposition of the great vessels. We present this case due to its rarity, and compare our pathologic findings with those already reported.
