Objective and method: To review the clinical and neuropathological findings as well as the type of therapy and outcome in 20 infants under 3 years-old with central nervous system (CNS) tumor. They were treated at the Department of Neurology, "Hospital das Clínicas" University of São Paulo Medical School, from January 1997 to May 2001.
Results: Astrocytoma was the most common histological type (n=7), followed by ependymoma (n=3), medulloblastoma (n=2), craniopharyngioma (n=2) and desmoplastic ganglioglioma (n=2). The location of the tumor was predominantly supratentorial. Mean follow-up time was 20.2 months with recurrence in 7 cases. For each type of tumor we have emphasized the treatment currently recommended.
Conclusion: Although follow-up time is not sufficient for analyzing survival, a trend of improvement in prognosis was noted, compared to another series of cases from our Institution that had been evaluated before 1990.
