Meningiomas

Meningiomas represent the most common intracranial tumor but also occur can occur within the spinal canal. The majority of meningiomas are benign (grade I), without recurrence following surgical resection with or without subsequent radiation. However, grade II and III meningiomas have a higher rates of recurrence and are fatal in some cases, hence requiring closer monitoring and a more aggressive post surgical treatment plan. This chapter discusses the etiology, risk factors, classification, clinical presentation, and management strategies for meningiomas, a tumor commonly encountered in neurologic practice.
