This coronal (from the front) T2-weighted MRI image shows a destructive soft tissue lesion in the middle ear (tympanic cavity) and mastoid antrum on the viewers left as seen as an area of brighter (whiter) signal. Cholesteatomas are usually the result of a perforation (tear) of the tympanic membrane (ear drum) with ingrowth of squamous epithelial cells which shed desquamated cellular debris and keratin. However they can be congenital .These are benign lesions which progressively enlarge and are locally destructive | |
