Temporal artery biopsy in herpes zoster ophthalmicus with delayed arteritis

A 58-year-old man developed herpes zoster ophthalmicus with delayed hemiparesis. Temporal artery biopsy confirmed the presence of a vasculitis. Electron microscopy of the temporal artery failed to reveal viral particles. Herpes zoster ophthalmicus with delayed arteritis appeared to be a contiguous spread of vasculitis to the carotid system and not a direct viral invasion.
