Introduction. Pediatric intracranial tumors (PIC) make up the most frequent solid neoplastic pathology in children. We present an analysis of the experience of Hospital Infantil de Mexico Federico Gomez (HIMFG), in Mexico City, over the course of 36 years in this regard. Material and methods. Cases from the archives of the Department of Clinical Records, Department of Neurosurgery and Department of Pathology at HIMFG were used for this analysis. Results were compared to data published by the Hospital for Sick Children of Toronto (HSCT) and by Instituto Nacional de Pediatria (INP) in Mexico City. Results. Of 810 cases reviewed at HIMFG, 55% belonged to the male gender. By age, older-infant and grade-school-children cases predominated (> 50%). Of those, 397 cases were supratentorial and 413 infratentorial. Most frequent tumors were: astrocytomas (23%), medulloblastomas , craniopharyngiomas (11%) and ependymomas (10%). Fifth place was occupied by germinomas (4%). Mixed gliomas, meningiomas, primitive neuroectodermal tumors and ependymoblastomas were the last (1 to 3%). Conclusions. At HIMFG, the most frequent tumour types were: astrocytomas, medulloblastomas, craniopharyngiomas and ependymomas. Since the 70s, on the number of patients presenting with intracranial tumors at HIMFG has grown exponentially, and the amount carried out till now at this hospital parallels, or slightly exceeds, that carried out at similar institutions in Mexico and abroad.
