I am surprised to hear you've had 4 craniotomies. I didn't know that was an option. I had a craniotomy 6 months ago for a meningioma that was almost 3 cm. and close to my optic nerve. I also have 2 other meningiomas that I need to deal with (now that I'm 6 months post surgery I'm mentally up to dealing with the other two) and I thought my only option was radiation, which scares me more than another craniotomy. Good wishes for you as you continue to navigate your health issues.
