[Dandy-walker syndrome]

The Dandy-Walker syndrome represents a cystic malformation of the posterior fossa. It occurs in 1/25000 to 1/35000 pregnancy. Antenatal diagnosis is based on obstetrical sonography. When the cerebellum abnormalities are associated to other visceral malformations, medical abortion can be indicated. We report in this work two cases of Dandy-Walker syndrome diagnosed during pregnancy. The aim of this study is to analyze modalities of diagnosis, obstetric management and outcome of this syndrome
