Vogt-Koyanagi-Harada syndrome: clinical and instrumental contribution

Vogt-Koyanagi-Harada syndrome is a rare disease, which probably has a cell-mediated autoimmune pathogenesis, marked by ocular (anterior and/or posterior uveitis), dermatological (poliosis, canities, vitiligo) and neurological (meningo-encephalitis) disorders of variable severity in variable combinations. The clinical pattern in the case reported here showed severe neurological involvement (headache, ataxia and confusional state) followed by anteroposterior uveitis. Instrumental investigations (cerebrospinal fluid, VEPs, BAEPs, EEG, CT and MRI brainscans) confirmed the diagnosis. The response to cortisone therapy was excellent. We emphasize the importance of the neuroradiological investigations, because of their peculiarities, and review the reports of cases with marked meningo-encephalitic impairment, given the dearth of reports in the neurological journals.
