<s>[INST] I just saw my neurologist who informed me I have a 7mm pineal cyst on the brain which I have had for some time. Also, my last two EKG s were negative. I have depression and anxiety and parkinsonism. I am currently on many meds and also suffer from chronic migraines which we are trying to get under control. Can you tell me or show me what the pineal cyst looks like? [/INST] I read your question carefully, and I understand your concern. I do not know if it is of much use to see a pineal cyst, you can't understand the significance of it without knowing brain anatomy, the surrounding structures and their function really. It is simply a fluid filled sac. If it doesn't compress any structures or obstruct fluid flow it doesn't cause any symptoms. If you really want to see how it looks like here is an MRI image where it is indicated by the arrows http://imgur.com/a/8lPFAI hope to have been of help. </s>
