Meningioma is a derivative of the meninges and meningeal space. It is the second most common intracranial tumor, accounting for 19.2% of all tumors, with a female:male ratio of 2:1. All intracranial areas rich in arachnoid granules and arachnoid villi are good sites for meningioma. Parasagittal sinus, cerebral convexity, and pars falcae are common, followed by pterygoid crest, pontocerebellar angle and cerebellar curtain, olfactory groove, and saddle nodes. Other sites are occasionally seen. Treatment of meningioma is based on surgical resection. In principle, complete resection and removal of the meninges and bone invaded by the tumor should be pursued in order to achieve radical cure. Meningioma is an extrinsic growth tumor, mostly benign. If it can be diagnosed early and operated before the tumor damages the surrounding brain tissues and important brain nerves and blood vessels, it should be able to achieve total resection. However, there are some advanced tumors, especially deep meningioma, which are huge and adhere to the nerves, blood vessels, brainstem and lower thalamus, or the nerves and blood vessels are not easily separated from each other. It is advisable to limit the tumor to subtotal resection, reduce the tumor volume, and supplement with decompression surgery to reduce the pressure of the tumor on the brain, relieve the intracranial pressure, and protect the vision. Or to be treated by staged surgery. For advanced tumors that cannot be removed surgically, after biopsy of tumor tissue, only decompressive surgery can be performed to prolong life. For malignant cases, radiotherapy can be used as a supplement. According to the growth location and characteristics, meningioma resection needs to cut off the surrounding meninges together in order to completely cure and prevent recurrence, but about 50% of the parts of skull base and meninges that cannot be resected can not be completely cut.
