The most common intracranial tumor is meningioma. The so-called meningioma is a benign tumor originating from the meninges, which can be cured by surgical removal. If the meningioma grows rapidly, or if it is large, removal may be risky. It is necessary to remove the meningioma in stages or after neoadjuvant radiotherapy. After radical surgery, postoperative radiation therapy as well as chemotherapy may be dispensed with. Intracranial tumors also include gliomas, which are also common intracranial tumors. If the glioma is superficial, it can be cured by radical surgery to remove it. In case of grade III and IV gliomas, simultaneous radiation and chemotherapy are required after surgery. Grade I and II gliomas. A postoperative strategy of observation can be adopted.
