A '''pineal gland cyst''' is a usually benign (non-malignant) [[cyst]] in the [[pineal gland]], a small [[endocrine gland]] in the brain. Historically, these fluid-filled bodies appeared on {{nowrap|1-4%}} of [[magnetic resonance imaging]] (MRI) brain scans, but were more frequently diagnosed at death, seen in {{nowrap|4-11%}} of autopsies.<ref name="Pu">{{cite journal |last1=Pu |first1=Y. |last2=Mahankali |first2=S. |last3=Hou |first3=J. |last4=Li |first4=J. |last5=Lancaster |first5=J.L. |last6=Gao |first6=J.-H. |last7=Appelbaum |first7=D.E. |last8=Fox |first8=P.T. |title=High Prevalence of Pineal Cysts in Healthy Adults Demonstrated by High-Resolution, Noncontrast Brain MR Imaging |journal=American Journal of Neuroradiology |volume=28 |issue=9 |pages=1706–9 |year=2007 |pmid=17885233 |doi=10.3174/ajnr.A0656 |doi-access=free }}</ref> A 2007 study by Pu ''et al''. found a frequency of 23% in brain scans (with a mean diameter of 4.3 mm).<ref name="Pu"/> |

The [[National Organization for Rare Disorders]] states that pineal cysts larger than 5.0 mm are "rare findings" and are possibly symptomatic. If narrowing of the cerebral aqueduct occurs, many neurological symptoms may exist, including headaches, vertigo, nausea, muscle [[fasciculations]], eye sensitivity, and [[ataxia]]. Continued monitoring of the cyst might be recommended to monitor its growth, and surgery may be necessary.<ref name="Nord">Pineal Cysts, Symptomatic, [[National Organization for Rare Disorders]]{{page needed|date=February 2016}}</ref> |

The National Organization for Rare Disorders states that pineal cysts larger than 5.0 mm are "rare findings" and are possibly symptomatic. If narrowing of the cerebral aqueduct occurs, many neurological symptoms may exist, including headaches, vertigo, nausea, muscle fasciculations, eye sensitivity, and ataxia. Continued monitoring of the cyst might be recommended to monitor its growth, and surgery may be necessary.[1] Tia is so gay tia is also so overdramatic and will not need open brain surgery the silly sausage
