Radiotherapy after tertiary surgery for meningioma is helpful in controlling the condition. Meningioma is a kind of benign tumor in clinic, which is usually solitary and grows slowly, may affect the surrounding tissues and nerves, and after growing to a certain extent, lead to headache, dizziness, nausea and vomiting due to the increase of intracranial pressure. Patients with meningioma can be treated with radiation after surgical resection, which can make the treatment of tumor more thorough and avoid re-growth and affecting the surrounding tissues. Surgery is the main treatment, but some patients may not be able to have the tumor removed completely because of the poor location of the tumor, so they may consider the combination of radiation therapy. For patients with grade 3 meningioma, it is recommended to consult the neurosurgery department of a regular hospital for treatment.
