Abstract
Dandy‐Walker malformation is an unusual finding in Meckel syndrome, which characteristically presents with encephalocele, polydactyly, and cystic renal disease. We report on a family in which three nonviable brothers had Dandy‐Walker malformations (variant) with associated enlarged cystic dysplastic kidneys and hepatic fibrosis. The consistent segregation of these abnormalities in all three sibs in the absence of polydactyly and encephalocele suggested the possibility of a distinct syndrome. The clinicopathological findings of the disorder are described and discussed in the context of the phenotypic spectrum of Meckel syndrome.
