Purpose: To demonstrate cochlear hyperintensity on a 3-dimensional (3D) fluid-attenuated inversion recovery (3D-FLAIR) sequence in a patient with incomplete Vogt-Koyanagi-Harada (VKH) disease. CASE REPORT: A 19-year-old woman presented with bilateral decreased visual acuity and headache, which was classified as incomplete VKH disease by the VKH Disease Revised Diagnostic Criteria. Magnetic resonance imaging (MRI) revealed bilateral choroidal thickening with retinal detachment, and bilateral cochlear hyperintensity was evident on a 3D-FLAIR sequence, which may have resulted due to involvement of the internal auditory system. CONCLUSION: We presented a patient with incomplete VKH disease and bilateral cochlear hyperintensity, evident on a 3D-FLAIR sequence. To the best of our knowledge, this is the first report of this imaging feature in the literature. This bilateral cochlear hyperintensity suggests minor hemorrhage or high protein content in the inner ears of our patient. This new finding might contribute to the diagnostic criteria for this rare disease.
