Hi Carol and welcome.
I'm sorry to hear you are having continued issues but glad that things have been narrowed down between micro-surgery vs. radio-surgery.
I'm not sure if you are located in the Duke area or elsewhere (or if you can or are willing to travel), but there are certainly many radio-surgery options to investigate. Like you, my AN is located deep in the IAC (left) and like you, I've ruled (and have been ruled) out microsurgery, so I am weighing all radio surgery options. My hope is that your dr can advise, based on your previous treatment, what kind of radiosurgery would be best.ÂÂ
Novalis (conventional radio-therapy)
Cyberknife
GammaKnife
Proton
Please research any and all options. Please discuss with NUMEROUS professionals (neurosurgeons, radio-oncologist, your primary care physician, etc). I have learned this past month that no question is too stupid, that I can ask all the questions I need to and remind myself that it's my head -- my brain -- not their's. Do any and all research you can. Many great posts on this site, great suggestions, other websites as well.
Please be well and know that we are ALL here for you.
Phyllis
