Meningiomas are common intracranial tumors, more than 80% of which are benign and grow relatively slowly. The magnetic resonance imaging features of meningiomas are relatively typical, and most meningiomas can be diagnosed by magnetic resonance. However, meningiomas are not non-growing. Meningiomas that have not been operated on need to be monitored closely and meningiomas that have been operated on need to be reviewed to see if they are growing and how fast they are growing. Meningioma review is mainly done by magnetic resonance imaging of the head, but determining the best frequency of review is a concern. Too long an interval between reviews may make it difficult to detect early changes in the tumor, and the tumor may grow to a large size by the time it is detected, missing the best time for treatment. If the interval between reviews is too short, it will waste too much manpower, material and financial resources, which is also unnecessary. For small and asymptomatic meningioma diagnosed by MRI without surgery, we should review the tumor once after 3 months to observe the change of the tumor, and if there is no obvious change, we can basically exclude the possibility of malignancy. For meningiomas that have been surgically resected, the pathology and malignancy of the meningioma can be clarified and a review plan can be made accordingly. Meningiomas of WHO grade II non-benign nature are reviewed after 3 months, then every 6 months for 5 years, and then annually thereafter if stable. Malignant WHO grade III meningiomas require review every 3-6 months depending on the rate of tumor growth. As to whether the patient needs to be reviewed in the same hospital for meningioma review, generally speaking, according to the current information system, the information and data of the patient’s review in the hospital are archived in the hospital, but cannot be viewed between different hospitals, so the information of the review in the same hospital is beneficial for the doctor to determine the changes of MRI through multiple comparisons. MRI reviews at different hospitals are also usually able to detect changes in tumor volume if they are more pronounced. Meningioma needs to be reviewed regularly, and the best review plan needs to be developed based on the imaging and pathology results to strive for early detection of possible growth changes of meningioma with minimal cost.
