Abstract

Dandy-Walker malformation is a part of Dandy-Walker complex and characterized as development anomaly of posterior fossa. Etiology is not definitely known. Many theories suggested as agenesis of Luschka and Magendie foramens, malformation of fourth ventricle root and delayed opening of foramen Magendie. Prenatal ultrasonography is important on diagnosis. Cystic dilatation of posterior fossa, hypo- or agenesis of cerebellar vermis is the main sonographic findings. Hydrocephaly may exist. This study reveals Dandy-Walker malformation with existence of hypoplasia of cerebellar hemispheres, meningocele and polyhydramnios.
