Acephaly is a congenital disorder characterised by absence of the head. Unlike anencephaly which is characterised by the absence of a major portion of the brain skull and scalp this type of cephalic disorder is even rarer. The acephalic fetus is a parasitic twin attached to an otherwise intact fetus. The acephalic fetus has a body but lacks a head and heart; the fetus’s neck is attached to the normal twin. The blood circulation of the acephalic fetus is provided by the heart of the twin.
