Meningiomas should be operated on in cases such as progressive enlargement or clinical symptoms. Meningioma is a kind of brain tumor originated from arachnoid capillary cells, and is most common in the cerebral hemispheres, such as the base of the skull, convexity, and paraspinal region. Most of the meningiomas are benign tumors. For meningiomas that are less than 2cm in size and asymptomatic, they can be closely observed and followed up regularly. If the tumor grows progressively or develops obvious clinical symptoms, it is necessary to go to the hospital immediately and choose surgical treatment and radiation therapy under the guidance of the doctor. It is recommended that patients with meningioma should seek medical treatment in time and choose the appropriate treatment plan under the guidance of the doctor, so as to avoid delaying the condition and causing serious consequences.
