I'm not sure if the surgeon was planning to do disk surgery at the same time? if that was the case it might be reasonable to take it out
without seeing the scan I cannot tell if is causign enough of a problem to take it out on its own
It is very slow growing and may or may not cause symptoms (like pinching a nerve) in the future
Because it is inside the dura, to get to it, a lmainectomy would probably need to be done
Getting a second opinion from a neurosurgeon is a good idea - they should be able to provide an objective opinion
Good Luck
I had a schwannoma discovered by accident about 4 years ago. It wasn't causing me any symptoms at all and was quite large. Following the advice of my neurosurgeon, I had it removed. Now I have nerve pain that I have to take Neurontin for daily. The recovery from the surgery was very painful. The tumor was the size of a lemon and wrapped around two nerve roots. He saved the nerve roots, but I was left with the pain. If I had it to do over again, I'd have left it alone until it caused me problems. Schwannomas will continue to grow, but they usually grow very slowly. They figured I'd had mine for 7-8 years or more. I pray you will be able to make an informed decision about surgery. Good luck!
