With the development of science and technology, the application of high technology in the clinic (such as computerized tomography (CT) and magnetic resonance imaging (MRI)) has made it possible to confirm the diagnosis of many difficult diseases, and many common headache symptoms are actually caused by intracranial tumors. Common intracranial tumors include gliomas, meningiomas, pituitary tumors, nerve sheath tumors, and metastatic tumors. The most common tumor is glioma, the higher the grade, the higher the degree of malignancy, grade IV glioma is also known as glioblastoma is one of the most malignant tumors in the nervous system, the patient’s survival period is usually about 1 year, individual cases can survive for more than 5 years. Meningiomas are mostly benign tumors that grow slowly, and some patients can grow to a large size without symptoms, which are often discovered when they go to the hospital with headaches and seizures. Most patients with intracranial tumors have headache, blurred vision, weakness or paralysis of one side of the limbs, inability to speak (aphasia) due to the compression of surrounding brain tissues and blood vessels caused by the increase in tumor volume, and some patients may have recurrent and intractable epileptic seizures (commonly known as crohn’s disease or epileptic seizures). Patients with nerve sheath tumors often have hearing loss on one side and numbness of facial sensation or loss of taste in one side of the oropharynx. These symptoms can be single or multiple, once appeared should be early medical treatment and cranial CT and MRI examination, if found occupying lesions should be early surgical treatment.
