[Clinical and diagnostic characteristics of brain tumors in children in the 1st year of life].

The clinical picture and diagnosis of tumors of the brain in infants of the first year of life are analyzed. Supratentorial tumors predominate (60%) at this age; 76% of the tumors were localized on the midline of the brain and grew into the ventricular system. The tumours were large and always induced the development of concomitant hydrocephalus. The disease was most frequently encountered among boys. The syndrome of progressive hydrocephalus comes to the forefront in the clinical picture and does not differ in clinical signs from that encountered in progressive hydrocephalus of nontumorous genesis. That is why every infant under the age of one year with hydrocephalus should be examined for tumor of the brain to exclude it as the cause. The diagnosis of brain tumors in infants of this age is extremely difficult and is possible only with use of a complex of additional radiocontrast methods of examination.
