Meningioma : An Overview

Abstract

Meningioma is an intracranial tumor derived from arachnoid meningothelial cells and the most common primary tumor of the central nervous system, accounting for approximately 36.3% of all brain tumors. Most meningiomas are benign and slow growing, but a small number can show atypical or malignant behavior. The main risk factors include radiation exposure, advanced age, female gender, and genetic disorders such as neurofibromatosis type 2. The diagnosis of meningioma is typically established through magnetic resonance imaging (MRI) and subsequently confirmed by histopathological examination. Management of meningioma involves observation, surgery, and/or radiation therapy, depending on the size, location, and clinical symptoms of the patient. The prognosis is generally good, especially in cases of benign meningioma that are successfully completely resected, although the risk of recurrence remains depending on the degree of malignancy and extent of resection. Long-term monitoring is still needed to detect recurrence and complication after treatment.
