Info

A solid mass is seen in the inferior aspect of the fourth ventricle. Mass shows no enhancement. No hydrocephalus. 

Also, there is an incidental arachnoid cyst in the left middle cranial fossa.

Case Discussion

The MRI findings are strongly suggestive of subependymoma of the fourth ventricle.

Subependymomas are uncommon, benign tumours which are usually small, typically less than 2cm in size.
