Audiography, X-ray (Stenvers view) and Magnetic Resonance Imaging (MRI) were performed on 88 patients exhibiting unilateral tinnitus. We diagnosed 4 cases (4.5％) of vestibular schwannoma and 41 cases (46.6％) of other abnormalities, including 2 cases of meningioma, 24 cases of old cerebral infarction, and 5 cases of mastoiditis.
MRI was considered to be a first-line clinical examination for patients with unilateral tinnitus.
Key words : magnetic resonance imaging (MRI), unilateral tinnitus, vestibular schwannoma
