The purpose of this paper was to analyze the anatomopathologic characteristics (location, histopathologic classification and gradation) of 233 Central Nervous System gliomas registered in the National Pediatric Neurosurgery Reference Center (Cuba), and to compare these results with other series from the literature.
Results: Gliomas represented 49,6 % of the total nervous system tumors diagnosed while collecting this series. The histopathologic gradation of the gliomas was: Grade I: 71, Grade II: 84, grades III: 64 and grade IV: 6. The histopathologic classification was: 107 grade I-II Astrocytoma; 51 grade III-IV Astrocytoma; 37 grade I-II Ependymoma; 21 grade III Ependymoma ; 7 grade II Oligodendroglioma; 3 grade II Oligoastrocytoma and 1 grade III Oligoastrocytoma. The locations of the gliomas were: 222 intracranial (127 supratentorial y 95 infratentorial) and 11 in the spinal cord. Male to female ratio was1.3:1.
Conclusions: Supratentorial gliomas were more frequent, different from other reported series. Pilocytic Astrocytoma was the more frequent glioma in this study.
