The hospital’s neurosurgery department, Yiji Mountain Hospital, Wannan Medical College, Jiang Xiaochun: Hello! Since I have not seen your imaging data, I cannot answer your question accurately. However, usually meningiomas should be more appropriately removed surgically. Stereotactic radiotherapy (r-knife, radio-wave knife, etc.) can be considered in the following cases: 1) old age and general health condition cannot tolerate surgery; 2) tumor is closely related to important functional areas and surgery is likely to cause serious complications; 3) tumor is less than 3 cm, etc. Radiotherapy is not a non-invasive treatment, and some patients may have severe cerebral edema or even radiation brain necrosis. Surgery and radiotherapy are both double-edged swords, there will be disadvantages if there are advantages. If you are from Shandong, we suggest you to visit the neurosurgery department of Shandong Provincial Hospital or Qilu Hospital, which are also considered very good in China.
