Overview

Pineal cysts are cysts of the pineal gland which is a small organ in the brain that produces melatonin (a sleep-regulating hormone). Pineal cysts are relatively common and may be found by chance in up to 10% of people undergoing CT or MRI brain imaging. The exact cause of pineal cysts is unknown. Most people with pineal cysts do not have any signs or symptoms.[1] Rarely, a pineal cyst may cause headaches, hydrocephalus, eye movement abnormalities, and Parinaud syndrome.[2] Treatment is usually only considered when a cyst is causing symptoms, in which case surgery, stereotactic aspiration or endoscopic treatment may be recommended.[3][4]
