[Hydrocephalus and craniodiaphyseal dysplasia (author's transl)].

One case is reported of dilatation of the lateral ventricles in a patient suffering from craniodiaphyseal dysplasia, with follow up of one year. The pathogenic hypothesis personally proposed are: a) partial and intermittent compression of the aqueduct by a dolico-mega basilar artery; b) "cisternal hypofunction".
