Abstract
Diprosopus is a rare congenital anomaly, characterized by partial or complete duplication of the craniofacial structure. It constitutes 0.4% of all congenital anomalies. Complete duplications are invariably associated with systemic anomalies. Here, we present such a case of diprosopus with complete duplication of face in a 24-week-old male fetus, associated with anencephaly and spinal rachischisis. Proposed theory of embryogenesis and associated anomalies are also discussed.
