Plain-English summary
A 10-year-old cat was brought in for signs of lethargy and balance issues, which were found to be caused by an invasive tumor in the middle ear called adenocarcinoma. This tumor was damaging the surrounding bone and even affecting the brain. Middle ear tumors are rare in cats, but they can lead to serious symptoms like chronic ear infections and vestibular disease (balance problems). Unfortunately, due to the aggressive nature of the cancer, treatment options may be limited, and the prognosis can be poor.

Abstract
Peripheral vestibular disease and lethargy were attributed to an adenocarcinoma in the middle ear of a 10-year-old cat. The tumor was invasive, inducing severe lysis of the tympanic bulla and adjacent temporal bone. Direct invasion to the meninges and brainstem also was observed. Neoplasms of the middle ear are rare in cats, with squamous cell carcinomas reported most commonly, but should be considered as causes of chronic otitis or signs of peripheral vestibular disease.
