Aural cholesteatoma is an epidermoid cyst filled with squamous material with keratinotic content that develops in the middle ear. The etiopathogenesis is not fully understood, but it is inferred that it is a rare complication of chronic otitis media or external. Thus, it is an uncommon condition and, therefore, little reported in dogs. Imaging tests, especially computed tomography, are important tools for the diagnostic approach. However, the confirmation of aural cholesteatoma is given through histopathological evaluation. The main therapeutic modality for this condition is the surgical removal of the lesion. Thus, this study aimed to describe a case of aural cholesteatoma in a bitch with a history of recurrent otitis. Clinical and computed tomography findings allowed for therapeutic and diagnostic planning. Therefore, the ablation of the left ear canal and the ventral osteotomy of the tympanic bulla were performed. The surgery allowed the collection of material for the histopathological examination, which determined cholesteatoma aural. The treatment allowed the complete remission of clinical signs and the definitive resolution of the recurrent otitis.
