Hi Brian,
I think Derek hit the nail on the head. Even if you have treatment, you still get to keep some or most of your symptoms, and you still get to have follow up MRIs off into the misty distant future, to be sure that it doesn't grow back. The bottom line is that ANs are not really fun. That said, you will get used to it, and find that you can still get on with life, whatever you may decide to do about the AN itself.
I will also add that there is a Cyberknife facility in Seattle, the Seattle Cyberknife Center, with a Dr. Vermuellen who is supposed to be good. So if you are looking into treatment options, you should look into radiation treatment as well. I went ahead and had mine radiated, with the hope of retaining the hearing I had left, which has worked so far, knock on wood. The tinnitus is with me for life, I suspect, but I don't really notice it any more. Life is good.
