A 44 year old woman referred to our ENT DEPT for the study of a progressive hearing loss in right ear (RE) and dizziness. Otoscopy showed by transparency a pinkish mass located on the bottom back of the tympanic cavity.
After imaging studies, a retroauricular surgical approach was performed identifying a mass that occupied the attic and it was closely related with facial nerve, promontory and oval window. Histopathology diagnosis was a salivary gland choristoma of the middle ear, a rare disease whose treatment depends on the degree of facial nerve compromise with the tumour. To our knowledge, this is the first report of labyrinthitis as a presentation of a middle ear choristoma.
