Great question Nancy Drew!!!
I was diagnosed a year and a half ago with a 9x11 AN, left side. 5 months later had another MRI, which revealed something, that wasn't specific, and only when I questioned that 5mm fusiform something or other, did the doctor feel it necessary to get better clarification. Back to the MRI machine to discover another mass, opposite side. It was diagnosed as a small Meningioma. I was told I would probably never have to deal with it in my lifetime, so not to worry about it. After sending my MRI's to House and to Stanford for expert opinions, the experts were divided. House said small meningioma, and not to worry, however Stanford said another An that should be treated with CK to preserve hearing since the first AN, right side has left me with 40% hearing.. So, had I gone forward with any type of procedure after the first diagnosis, my decision may have been different had I known about the second tumor. I sit presently waiting for my next MRI which had been scheduled for July 6th but I cancelled due to Pneumonia, and coughing which would not allow me to be still! My point is, and I mentioned this to you before, timing is very important if the timing is right for you. As a W and W, I am very apprehensive and emotionally somewhat of a mess. I am not by-polar, but I do get very down about this situation. I need to know for sure what and where this other tumor is for sure, as I have absolutely no symptoms with it. I think your tagline after your name is a good one Wait and Watch and Wonder! I believe that says it all! I wish you the best and look forward to your questions as I find them valid, not silly. You are like alot of us we have inquiring minds and don't blindly follow the advice of the physicians! I praise all the Aner's that have gone before us they have helped pave the way for this journey that is such a challenge.
God-luck to all and much love to all
