I, like you suffer from a large Pineal cyst about 20mm in size. I have all the same symptoms you have with very little change in 6 years now. My grandmother died of a hemmmorage of the vein of galen due to pressure from the pineal glan as referenced by an Autopsy performed on her in 1964. She was 48 years old. I am 41 and am becoming more and more symptomatic. I trust my neurosurgeon and know I will have the surgery within 4 years as he will be retiring at that time. I really wouldnt want anyone else to do my surgery. My name is Nancy and my cell phone number is 469-964-0901 if you ever want to talk.
