A pineal cyst is a fluidic cyst that grows in the pineal gland. They are normally harmless and benign and are not tumours. The cause of pineal cysts is unknown. Most cysts do not become larger but some may enlarge over time.
For most cases of pineal cysts, there are no symptoms as they are asymptomatic. In most cases, pineal cysts are discovered when an MRI and CT scan is done for some other purpose. In some cases where larger cysts are involved, there can be a few symptoms such as:
- Visual symptoms
After diagnosis, in most cases, treatment is not required however; MRI scans will be done to check whether the cyst is growing. If the patient is receiving symptoms from the cyst, it may need to be surgically removed.
