My 90 year old sister was diagnosed several years ago with an acoustical neuroma and has been followed with MRI's yearly. Main symptom was dizziness every once in a while and hearing loss. In the past few weeks she has had several auditory hallucinations and c/o dizziness all the time. Is verbalizing she wants surgery and says she can't live with what she is experiencing! Could these symptoms be due to the neuroma? She is NOT a good surgical candidate. Is there some other option?
