Statisically, these fluid-filled bodies appear on 1-4% of [[magnetic resonance imaging]] (MRI) brain scans. They are more frequent at death, seen in 21-41% of autopsies, though researchers are not sure why. They are in most cases asymptomatic, and it is rare for a pineal cyst to cause symptoms. If they do, these would most likely be headache, visual disturbances, or [[hydrocephalus]], which can be extremely dangerous if left untreated. Pineal cysts are '''not''' cancer and most of the time they do not enlarge over 2 centimeters. Asymptomatic cysts require no treatment. Some doctors choose to monitor patients with [[CT scan]]s or MRI to look for cyst growth, but most doctors do not{{fact|date=June 2007)).
