Vogt-Koyanagi-Harada's disease presenting polymorphonuclear pleocytosis in the cerebrospinal fluid at the early active stage.

We report a 16-year-old woman with Vogt-Koyanagi-Harada's (VKH) disease, presenting polymorphonuclear pleocytosis in the cerebrospinal fluid (CSF) and neurological manifestation similar to meningoencephalitis. VKH disease, which has severe neurological manifestations including numerous CSF polymorphonuclear pleocytosis, should be considered as a differential diagnosis from infectious meningoencephalitis.
