Just wondering how it came to be that you discovered that you have an AN. Were you having any symptoms or was it found by accident? Mine was found by accident in 2005. I was having vertigo, and I couldn't walk because the spinning was so bad. My ENT decided to see what was going on and sent me for a MRI. The AN was found. Samll 4 mm x 5mm. He sent me to the AN doctor, and he was confused about the vertigo because that isn't usually a presenting symptom (hearing loss is usually what brings one to get the diagnosis). I had hearing pretty much in the normal range with hearing actually better in my AN ear than the other. He thought the vertigo was caused by migraines without the headache. I have a history of migraines, but I had never had vertigo, especially like this, with my usual migraines. I have bipolar disorder, and I had been experiencing depression at the time after years of stability. My psychiatrist had gradually increased my Lamictal (an anticonvulsant) level over time, and he was confused about the vertigo and decided to do a Lamictal level. It showed that I had a level above the normal limit and higher than any level he had ever seen in his practice. As soon as the medication was reduced to my usual dose, the vertigo completely went away. So, the AN was indeed found by accident. I thought the AN would never grow so I just didn't think much about it except around my annual MRI. No growth for MRIs one through four. Slight growth and bothersome hearing loss occured this past year. The doctor recommends that I have the gamma knife. I am awaiting a second opinion from a team of AN experts. Should get the results soon. So, it is hard to say what I will be doing at this point since I have only one doctor's opinion. I have researched some, and if I do decide on treatment I will probably go the GK route unless someone can convince me otherwise. Waiting and watching still sticks in my mind though. I have had all of my MRIs done at the same facility, with the same machine, and same person doing the MRIs. One- three MRIs read by different docs, and the AN was stable along with my hearing. Four and five were read by the same doctor. Fourth was the same as one thru three, and then the fiifth showed slight growth along with some hearing loss. My doctor said the AN would probably continue to grow with my age (49), and of course whatever hearing loss I have from here on out is hearing I will never get back. With GK hearing could stay the same, get worse or I could lose it altogether. You will read stories here that are successful and not so successful so it is a hard decision to wait and watch or go for treatment. For me this whole process seems like mental torture because there is no guarantee with any of these treatments. So, just all I can suggest to you at this point is to continue to research, keep on asking your doctor questions, and get a second opinion or more if that will make you feel better. This whole process is freaky, and I totally lost it when I found out I had the AN, and I am now freaking out even more now that it is growing and the hearing is affected. Keep up with this board if it brings comfort to you. Sometimes I think it is ok to take a break especially if you don't have any symptoms that really bother you. Best wishes, and I hope my story sheds some light on what it is like to wait and watch.
