title: Twins with acardia and anencephaly.
abstract: The authors describe a pair of twins, one of whom showed acardia while the other had severe neural tube defect including anencephaly. This is the first observation of a fetal malformation (anencephaly) in the cotwin of an acardius and confirms the fact that even the cotwin of an acardiac fetus may be at risk of severe congenital malformations.
