Abstract
Posterior cranial fossa meningiomas represent approximately 9% of all the intracranial
meningiomas. Despite the recent reports of radiation therapy in the management of
these tumors, surgical resection continues to be the first line of treatment method
aiming the permanent meningioma eradication. The evolution of imaging studies improved
the preoperative evaluation of meningiomas providing greater anatomical detail of
small structures not previously visualized. Nonetheless, the preoperative radiological
evaluation should go beyond the differential diagnosis of a posterior fossa tumor.
Anatomo-radiological assessment of meningiomas is discussed in detail. Based on our
clinical experience, literature review, and case illustration, we highlight important
preoperative anatomo-radiological aspects of posterior fossa meningiomas and their
implications in the surgical management of these tumors.
