Unlabelled:
Meningiomas are the most frequent met intracranial tumors. Many authors tried to order them according to location, origin and histopathologic type.
Material And Method:
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).

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
