Extensive sclerotic bony expansion with a groundglass appearance involving the left zygoma, sphenoid and petrous temporal bone.
The bony expansion is centred on the medullary bone and has abrupt transition zones.
Almost complete bony stenosis of the left external auditory meatus down to 1-2mm with consequential fluid in the external auditory canal and middle ears. Ossicular chain intact.
The left mastoid air cells are under-pneumatised, and completely occupied by fluid.
The left internal auditory canal is normal, however, the bony expansion involves both the tympanic and mastoid segments of the facial canal which are obliterated/stenosed.
