We report a case of hemorrhage from brainstem cavernous angioma that caused various symptoms including neurootological, gustatory and facial sensory disturbances. A man experienced nausea and numbness of his right ear. It was confirmed that the symptom were derived not from a peripheral lesion but from retrocochlear and brainstem impairment based upon the findings of the DPOAE, ABR, VEMP, caloric test, optokinetic nystagmus etc. We detected an area of retrocochlear lesion that was responsible for both the auditory and vestibular disturbances based upon detailed neurootological examination in addition to MRI findings, and showed that the impairment was improved one year later without specific treatment.
