On my 6 month MRI, mine did grow. I will have another MRI in July and see how much it has grown this time. Since I still have hearing in my left ear and it is fairly small, my neurosurgeon suggested I wait but was good with whatever option I decided. My AN is farther from brain (which I thought would be good but apparently not). I will lose hearing immediately after surgery. These are the reasons why I have decided to wait. They never mentioned it would stop growing. It’s just a matter of how big do I let it get before removal. Also, he did say that your brain can “adjust” slightly to your new normal. Last summer my symptoms did seem to get a little better for a few months. Symptoms started back again in oct and have gotten worse in the last month again.
