Contralateral hemiparesis following herpes zoster ophthalmicus.

A case of herpes zoster ophthalmicus was followed, after a latent period of four weeks, by contralateral hemiparesis. An attempt is made to clarify the anatomical relationships involved in the pathogenesis of postherpetic cerebral complications. Detailed presentation of neuropathological findings in this case may provide evidence of vasculitis in the syndrome, with better understanding of the pathological anatomy.
