ABSTRACT
Background: Primary tumors of the central nervous system represent about 2% of total adult malignancies and 20% of all malignancies in children. After the leukemias are the second most common childhood cancer.
Objective: To determine the frequency and radiological correlation with clinicopathological behavior of posterior fossa tumors in children treated at the Hospital San Jose Tec de Monterrey.
Material and methods: descriptive study, carried out based on hospital records of 47 pediatric patients diagnosed with posterior fossa tumors treated at the Hospital San Jose Tec de Monterrey in January 1990 to May 2009. Variables were: age, sex, clinical features, location, extent of tumor and histological type, measures of central tendency, dispersion, position, quantitative variables and the observed frequencies for qualitative variables.
Results: The highest percentage of posterior fossa tumors occurred in the age group of 1 to 5 years (21) and 6 -10 (13), which represented 45 and 28% respectively. The major statistical volume of posterior fossa tumors was astrocytoma (34%), followed by medulloblastoma (21.3%), ependymoma (19.1%), glioma (12.8%), oligodendroglioma (4.3%), ganglioglioma, meningioma, hemangioblastoma, papilloma choroid plexus (2.1%). The initial symptoms experienced by the patients with posterior fossa tumors were headache and vomiting (40.4%) and only vomiting (25.5%). 53.2% of patients had no accompanying symptoms.
Conclusion: Over the years the frequency by sex and age group remains the same, like tumor diagnosis by computed tomography or magnetic resonance imaging with contrast have had the same behavior described in other series.
