Secondary manifestations of glioma include symptoms such as nausea, headache, vision loss, and seizures. Nausea and headache are manifestations of intracranial hypertension caused by glioma. Vision loss may be due to optic nerve atrophy caused by tumor compression of the optic nerve, or optic papillary edema secondary to optic nerve atrophy due to intracranial hypertension. Epileptic symptoms may be caused by tumor compression leading to swelling and edema of the surrounding brain tissue, which puts the peripheral nerve cells in an allergic state and makes them prone to sudden, transient discharges. Glioma grade II is a low-grade, benign glioma with a better prognosis and longer survival than grade III and IV gliomas. Treatment is based on surgical resection, and radiation therapy can be continued if there are residuals after surgery. When glioma is found, it is necessary to improve the relevant examination in time and standardize the treatment under the guidance of the doctor.
