Abstract
A 67-year-old woman developed clinic al findings consistent with herpes zoster of the left ear, localized encephalitis and meningitis. These signs included herpes of the left external ear and soft palate, VIIth and VIIIth nerve disfunction, ataxia and electro-nys-tagmographic (ENG) abnormalities ; defective opto-kinetic nystagmus and saccadic pursuit towards the right.
Treatment with adenin arabinoside (Ara-A) resulted in rapid improvement.
The importance of CSF examination including cell counts and CSF-IgG index, ENG and EEG was emphasized.
