Hi I had one removed two years ago April 18th. It was successful with some minor defects. What size is your? Where is it located? Do you currently have symptoms from it? How did they find it? Do you have a neurologist? Is it going to be removed? Mine was rather large & was causing lots of major problems & disrupting my daily quality of life when I wasn’t sleeping 20/22 hours a day. My surgery was successful with a few permanent defects.
