XXXX of the ear. A locally destructive benign lesion.

@entity1 @entity1313 @entity5 @entity6437 @entity2319 @entity281
We describe three cases of a fibroinflammatory @entity6437 (tumefactive fibroinflammatory lesion) of the middle and inner ear. The @entity1 presented with @entity2319 in the affected ear and no response to caloric stimulation. The computed tomographic pattern showed destruction of inner ear structures and a typical widening of parts of the labyrinth. Magnetic resonance imaging performed in all three @entity1 showed an extension greater than expected based on computed tomographic images of both areas of destruction, as well as areas of radiologic normality. An enhancing mass was seen in the inner ear with a characteristic extension into both the internal auditory canal and the middle ear. A transotic approach or subtotal petrosectomy was used to remove the @entity5 in all three cases. Although histologically benign, these @entity5 are locally destructive and, as such, behave like a @entity1313 . They are composed of fibrovascular tissue admixed with chronic inflammatory cells. To our knowledge, this is the first report on @entity6437 of the middle ear, inner ear, and internal auditory canal. @entity6437 used to be a somewhat confusing term for a recognized entity of unknown origin. It is likely that @entity281 is an important contributing factor in the development of these lesions. Although surgical removal seems to be the treatment of choice, no clear judgment of its prognosis can be made owing to the rarity of this @entity5 .
