Abstract:
Two cases of vestibular disturbance caused by residual oily contrast medium in the internal auditory canals after myelography are reported. Nystagmus towards the affected side and normal caloric responses were observed; therefore, contrast media are considered to act as irritants to the vestibular nerve.
