Meningioma is a common benign intracranial tumor, accounting for about 15% to 20% of intracranial tumors, second only to glioma. Near the sagittal sinus, the brain is convex, and the brain is more common than the sickle, followed by the sphenoid crest, sella tuberosity, olfactory groove, cerebellopontine angle and tentorium. It is rare to grow in the ventricle, and it can also be seen in hard Outside the membrane. Occasionally in other parts. If the meningioma is small and the patient has no symptoms at all, such as limb movement, sensory disturbances, and no seizures, then there is nothing to do, just regular review, no medication or infusion. In daily life, there are no special requirements for food, work and rest. It is good to go to the hospital to review CT or MRI at a fixed time. However, there are some meningiomas that do not need to be treated. When imaging studies find that it is very close to the optic nerve, such patients should pay close attention to changes in vision in their daily lives. Once there are problems such as double vision or blurring, go to the hospital for treatment as soon as possible. If there are no symptoms, should I go for a review? Yes, as long as there is a meningioma, it must be reviewed regularly. After all, some tumors can grow very large without causing any discomfort; if you wait until you have obvious symptoms and then check, the tumor is likely to be very large, which will bring a lot of trouble to the operation. If one or two years of observation, the meningioma has not changed much and has no symptoms, can it be left alone? If a meningioma is accidentally discovered, it is recommended to review it after six months; if there is no change after six months, and there is no discomfort, you can review it every other year. Until the tumor grows up or when symptoms appear that require surgery. It cannot be said that after one, two, three or five years of re-examination, there is no obvious change, so we will no longer care about it. Meningiomas need to be reviewed and followed up for life.
