Dandy-Walker malformation in the Meckel syndrome.

The Meckel syndrome is an autosomal recessive condition and includes a heterogeneous group of CNS malformations, most frequently occipital encephalocele. We report on 2 sibs and one other unrelated case with Meckel syndrome in whom the CNS anomaly was the Dandy-Walker malformation, an association not previously described. The criteria used to diagnose the Meckel syndrome are also reviewed.
