Meningiomas are tumors that originate in the meninges and meningeal spaces. It may originate from dural fibroblasts and soft meningeal cells, but most originate from arachnoid cells. The population incidence of meningioma is 2 per 100,000. They are mostly found in 1. parsagittal sinus; 2. saddle node; 3. cavernous sinus; 4. pontocerebellar horn; 5. cerebellar curtain. Headache and epilepsy are the first symptoms. Depending on the location of the tumor, visual acuity, visual field, olfactory or auditory disorders and limb movement disorders may also appear. The symptoms of increased intracranial pressure are not obvious, especially in elderly patients. The tumor near the skull can cause bone changes, which can make the local skull thinning, destruction, or even invade the skull, and is a local bulge of the scalp. It can also thicken the inner plate of the skull, and the thickened skull can contain tumor tissue. Surgical resection is the most effective treatment. With the development of microsurgical techniques and continuous improvement of surgical instruments, the surgical effect of meningioma has been improved, enabling most patients to be cured.
