[Combined deformity of the brain and cerebral vessels (congenital hydrocephalus) in a 3-year-old child: dandy-walker syndrome, arteria primitiva trigemina and haemangioma (author's transl)].

In a 3-year-old child, a rare combination of a Dandy-Walker syndrome, a primitive trigeminal artery and a facial haemangioma was found. These multiple dysplasias originate from different germinal layers and result from disturbances of different periods of gestation.
