This axial (cross sectional) contrast enhanced T1 weighted MR image shows a non enhancing hypointense mass like region in the prepontine cistern with compression of the brainstem. This represents an epidermoid tumour/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. | |
