Hi,
How is your son? Are there other symptoms present? As mentioned from the other post, a pineal cyst is a fluid-filled growth inside the pineal gland. This is usually benign in nature and asymptomatic. However, a cyst may enlarge and press on surrounding structures causing symptoms such as headaches and blurred vision. This  can be removed through surgery. Do keep us posted with your neurosurgeon consult. Take care always.
