A case of brainstem cavernous angioma associated with hearing loss and dizziness is reported. A 25-year-old female initially complained of hearing loss in the leftear and dizziness. Six months thereafter she suddenly developed additional symptoms, and was diagnosed as having hemorrhage in the brainstem on the basis of CT scan and MRI findings. Otological examination revealed low- and high-frequency hearing loss and abnormal ABR consisting of only wave I in the left ear. Follow-up MRI showed cavernous angioma, which was surgically removed.
