Intracranial space-occupying disease is commonly known as intracranial growths, also known as intracranial tumors. The treatment of intracranial tumors is mainly based on surgery, which needs to be supplemented by radiotherapy, chemotherapy, biotherapy and other comprehensive treatments according to the nature of the tumor. Intracranial tumors are characterized by increased intracranial pressure, such as headache, vomiting and optic papilla edema in the early stage. Specific clinical features may also appear according to the different locations of its occurrence, for example, patients may have epilepsy, cerebral nerve palsy, hearing loss, limb instability, nystagmus and other manifestations. Adjunctive examinations in the early stage of intracranial space-occupying lesions mainly include head CT, head magnetic resonance scanning plus enhancement, and so on.
