Abstract
When examining patients who present both fluctuating auditory symptoms and vestibular symptoms, which can be mistaken for an ear disease, it is important to consider cochlear-carotid fistula as a condition that could generate these clinical manifestations. In this case, additional imaging tests should be performed to demonstrate the lack of continuity at that level and rule out other entities. The objective is to describe the cochleo-carotid dehiscence in a 39-year-old woman and propose it as a possible etiology of a third window syndrome, in order to discuss the relationship between clinical findings, neurotologic examination, and magnetic resonance imaging.
