Hi there,

Sorry this is a really delayed reply but just came across the post now, perhaps others will find it useful as well. I had a cyst discovered on my pineal gland as well. The specialist (neurosurgeron) I was seeing advised it was not causing my post-concussion symptoms and that it is not uncommon to find cysts on the pineal gland as an incidental finding. He did recommend to get another scan done 1 year after the first MRI and then a third scan 2 years after the second; just to ensure it did not grow in size. I have completed all three of these scans now and thank God there have been no issues.

I'm not sure how large mine was so I cannot comment on size, but based on the reading I did and what my physician advised me, it seems pineal gland cysts usually do not cause problems.
