Patient Data

Age: Elderly adult

Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.


Within the inferior aspect of the fourth ventricle is a small well-circumscribed mass that is isointense on T1 to the adjacent cerebellum and slightly hyperintense on T2. There is no evidence of calcification or contrast enhancement. No hydrocephalus is identified.

Case Discussion

This is a typical appearance and location of a subependymoma. In the correct demographic (older adults) typical appearances such as this should be reassuring and enable conservative management, as long as the patient is asymptomatic.
