-Taken as proved that brain tumors are the second most frequent childhood neoplasm -only outnumbered by leukemias -we have undertaken a clinical perspective study with seventy brain tumor patients ranging from one to fifteen years of age, throughout a four-year period (1993)(1994)(1995)(1996)(1997), based on ambulatoryoriented follow-up. Forty-one male and twenty-nine female patients were analyzed, in that a slightly higher number of infratentorial tumors was observed (thirty-eight cases), compared to those supratentorially located (thirty-two cases). The most repeatedly observed during the study was the medulloblastoma (twenty-one patients), followed by the astrocytoma (fifteen patients) and the germinoma (eleven patients). It should be pointed out that during the ambulatory follow-up 75,5% of patients developed neurological sequels. A tumor recurrence was noticed in 34,3% of them, while 21,4% eventually died.KEY WORDS: infratentorial, supratentorial, sequels, brain tumors. Avaliação neurológica de crianças e adolescentes com tumor cerebral através de acompanhamento ambulatorialRESUMO -Considerando que os tumores cerebrais correspondem à segunda neoplasia mais freqüente na infância, sendo apenas superados pelas leucemias, realizamos um estudo clínico prospectivo em setenta pacientes com tumor cerebral, com idade variando de um a quinze anos, por um período de quatro anos (1993)(1994)(1995)(1996)(1997), através de acompanhamento ambulatorial. Avaliamos quarenta e um pacientes do sexo masculino e vinte e nove do sexo feminino. Observamos uma freqüência discretamente maior de tumores infratentoriais (38 casos) em relação aos de localização supratentorial (32 casos). O tumor mais freqüentimente observado foi o meduloblastoma (21 casos), seguido pelo astrocitoma (15 casos) e pelo germinoma (11 casos). No acompanhamento ambulatorial, observamos que 75,5% dos pacientes evoluíram com sequelas neurológicas. Em 34,3% houve recidiva tumoral e 21,4% dos pacientes evoluíram para óbito.
