Plain-English summary
An 8-year-old male neutered Siamese cat was brought in with a head tilt and signs of Horner syndrome, which can cause drooping of the eyelid and pupil constriction. The vet found a mass in the cat's ear and performed surgery to remove it. Tests revealed that the cat had an ear infection along with a cholesterol granuloma, which is a type of growth that can occur in the ear. After treatment, including addressing the infection, the cat's symptoms improved.

Abstract
An 8-year-old, male neutered Siamese cat was presented with Horner syndrome and right head tilt. A soft tissue mass was observed in the right tympanic cavity, and bulla osteotomy was performed. Tissue samples retrieved from the tympanic cavity were sent for histology, and a middle ear fluid swab was sent for bacterial culture and sensitivity. Histologic diagnosis was of otitis media associated with cholesterol granuloma (CG). Bacterial culture yielded Pasteurella multocida and Leifsonia (Corynebacterium) aquaticum. Middle ear CG is frequently seen in human beings and is associated with a variety of middle ear diseases including otitis media. Cholesterol granuloma of the middle ear has been experimentally induced in cats. The clinical and pathological findings of a spontaneous case of CG in the tympanic cavity of a cat with otitis media are described herein.
