A simple pineal cyst is again demonstrated stable and measuring 10mm in its anteroposterior axis. There is no nodular wall thickening or abnormal features that raise suspicion. Remain brain is unremarkable. 

Case Discussion

Pineal cysts are common, usually asymptomatic, and typically found incidentally. Their importance is mainly in the fact that they cannot be distinguished from cystic tumors, especially when large or when atypical features are present.

Cases such as this one are included in a controversial discussion whether an imaging follow-up is really necessary or not. To avoid patient's anxiety or even unnecessary money expenditure in the future, this case's report conclude: "The simple pineal cyst remains stable. No atypical features are present".
