Meningioma occurs most frequently as a benign tumor central nervous system that is common in old females. Radiation exposure and deletion of the NF2 gene are known risk factors. However, there is no consensus about the role of sex hormones. Meningiomas are usually benign tumors, but 6% can be anaplastic or atypical. Most asymptomatic patients do not require treatment, but complete surgical resection is recommended for symptomatic patients. If a tumor returns after being resected previously, it is recommended to be resected, followed by radiotherapy in some cases. Meningiomas (benign, atypical, and malignant) recurring after standard treatment fails could be treated with hormone therapy, chemotherapy, target therapy, and calcium channel blockers.
