- axial projection showing partial opacification of the right middle ear cavity, namely the epi and mesotympanum, by isoattenuating soft tissue density extending to the aditus ad antrum and ipsilateral mastoid air cells. This is associated with blunting of the scutum, erosion of the posterior facial nerve bony canal, as well as ill-definition of the anterior crura of the right stapes, consistent with right chronic otomastoiditis with cholesteatoma formation
- axial and coronal projections showed abnormal morphology of the semicircular canals bilaterally with bilaterally widened and shortened lateral semicircular canals, small fragmented central bony islands, and dilated vestibules
