[Posterior fossa meningiomas--topographic and anatomopathologic aspects].
Meningiomas are the most frequent met intracranial tumors. Many authors tried to order them according to location, origin and histopathologic type.


METHODS
Our study is focused on posterior fosa meningiomas, initially classified according to their origin based on IRM and surgical findings in order to identify correlations between demographic data, topographic tumor origin and anatomopathologic characteristics for each subgroup. 35 posterior fosa meningioma patients that have been subject to neurosurgery in Iaşi "Prof.Dr. N. Oblu" Hospital Neurosurgery Clinic between January 1st 2005 and December 1st 2009 were assessed.


RESULTS
In our study group the majority of patients were females, with an average age in their early 60's. Benign meningiomas (1st degree) represented the unique subtype in tumors located in cerebellum convexity and foramen magnum. Other locations have different characteristic subtypes (fibrous vs. angiomatous meningioma).
