I have been a doctor for many years, and lumbar neurilemmoma needs spinal surgery. As far as I know, the Third Hospital of Peking University is the national authority on spine! To say the best, I think it is the best there, and of course Jishuitan Hospital is also good!
The cost is about 30-50 thousand! The specific price depends on your MRI and surgical plan. You can ask or call with the information!
