Four views of the feline head are provided: open jaw, ventrodorsal, and two lateral oblique.

The wall of the left tympanic bulla is thickened and irregular. The osseous proliferation appears laminar and outward-growing.

High on the differentials list is otitis interna.

There is thickening of the left bulla with radiopacity within the bulla.
This cat had a nasopharyngeal polyp.
Nasopharyngeal polyps originate in the middle ear and the eustachian tube. Clinical signs are nasopharyngeal, signs of otitis or both. Horner's syndrom and otitis interna are possible complications.
