This sagittal (from the side) T1 weighted MR image shows a heterogeneous low signal intensity mass in the fourth ventricle. This represents an epidermoid cyst which is a congenital lesion consisting of keratinized epithelium with desquamation. These expand/grow over time. This is the same as a congenital cholesteatoma. | |
