A 28-year-old man presented with a 2-week history of vertigo and tremor of his right arm. The symptoms were episodic. A neurologic examination revealed weakness and a postural and intentional tremor of the right hand. Audiometric evaluation demonstrated a downsloping sensorineural hearing loss in the right ear. Auditory brainstem evoked responses were also abnormal in the right acoustic pathway between the acoustic nerve and the inferior nuclei in the pons. The left ear was normal.
