My 22 YO son was diagnosed via imaging w/ a CN – from my research (Dr Google is scary), there are about 30 a year. No standard of treatment that’s agreed on. Read about gamma knife, endoscopic surgery, etc. I have an appt next week at Mayo here in AZ but they can’t tell me if the surgeon has done this procedure before. Does Mayo have a way to determine if one of their docs has treated this before. There are papers by neuroradiologists but none by surgeons online I can find. I will take him to Minnesota to get this treated by a physician who has actually tackled this tumor in the past. Thanks in advance.
