Years ago, I was friends with another brain tumor survivor who experienced hallucinations after having an awake craniotomy. She either had a grade II or grade III, I don't remember. I can't even imagine being woken up during my brain surgery!! I had an intraventricular pilocytic astrocytoma. My surgery dates back to 1992. Overall, how are you? Is this a wait & watch? Please keep me updated. Thanks.
