The authors analyze 106 intracranial tumors occurring in patients from 0 to 15 years of age. This study was carried on during the period from 1962 up to 1977. In 85 cases the diagnostic work up was made on clinical, radiological, and histological grounds; the remaining 21 cases had their diagnosis based solely on clinical and radiological evidence. Observations involving incidence according to age, sex, localization and histological types are made. The signs and symptoms and supplementary examination are discussed. The frequency of primary intracranial tumors in children under 1 Year of age is stressed.
