Intracochlear neurinoma was found in a patient in whom audiometric study, 6 months before death, had shown symmetrical hearing loss of the perceptive type. In the author's opinion the neurinoma cannot have been responsible for this hearing loss, as the labyrinth showed only slight histological changes. Many other factors in the patient's history may have caused the hearing impairment. The tumour was found to have no relation to the vestibular branch of the acoustic nerve.
