Pineal cyst

Common Name(s)

Pineal cyst

Pineal cysts are cysts of the pineal gland, a small organ in the brain shaped like the seed of a pine cone that is responsible for making melatonin, a hormone that regulates sleep.  Pineal cysts may be found by chance in up to 10% of people undergoing CT or MRI brain imaging, and they occur in three times more women than men.  Most pineal cysts do not cause symptoms and stay the same size over time (remain stable).   In the rare circumstance where a pineal cyst does cause symptoms, it may cause headaches, hydrocephalus, eye movement abnormalities, and Parinaud syndrome.   Because most pineal cysts do not grow or cause symptoms, there are no established guidelines for routine follow-up for individuals with pineal cysts.  Treatment is usually only considered when a cyst is causing symptoms.   In the past, treatment for symptomatic pineal cysts included surgery to remove the cyst (craniotomy); more recently, less invasive procedures such as stereotactic aspiration or endoscopic treatment have been recommended.

Author(s): S Fakhran, E J Escott

Journal: AJNR Am J Neuroradiol. 2008 Jan;29(1):159-63.

 

Pineocytomas have been described as well-circumscribed, homogeneously enhancing masses. However, there is considerable variability in this appearance, and certain pineocytomas may have a predominantly cystic appearance on imaging. This has led some to suggest that differentiation ...
