Meningiomas are very common, accounting for 15.31% of intracranial tumors, second only to gliomas. They are more common in adults, less common in the elderly and children, and even less common in infants and young children. They are slightly more common in women than in men. They are benign tumors that occur in meningeal cells and are also a very important tumor in the eye socket. They are valued by ophthalmologists and neurologists because of their high incidence, severe damage to vision, wide range of invasion, easy spread to bone canals, bone fissures and bone walls, and frequent recurrence after surgical resection, and even cause death. It is worth noting that it is difficult to determine the primary location of some tumors.
