Seventy-six children were studied who had been operated on for intracranial tumors; they ranged in age from 0 to 2 years. Twenty-nine cases were under 1 year and 47 between 1 and 2 years of age. The outlook was relatively poor regarding the highly malignant tumors, but surprisingly encouraging in benign and low-grade malignant neoplasms. The undesirable effects of complementary oncological treatment in this age category are stressed. On the other hand the importance of radical surgery is emphasized as the best treatment for these lesions.
