[Dandy-Walker syndrome].

Two cases of this syndrome occurring in children aged 1.5 and 3 years are reported. In one case, no other abnormalities were present, and the deformity did not manifest itself clinically before the child had fallen from a height. In the other, a cyst of the fourth ventricle coexisted with other abnormalities in the brain which were responsible for neurologic symptoms from the very birth and also, probably, for the atresia of draining orifices.
