Delayed central neurological symptoms following herpes zoster ophthalmicus (HZO) such as "herpes zoster ophthalmicus and delayed contralateral hemiparesis" are considered to be due to ipsilateral intracranial vasculopathy. We experienced a rare case with cerebral infarction occurred in puerperium following HZO in late pregnancy. A healthy 30-year-old woman had left HZO at weeks 35 of gestation. She was given acyclovir (ACV) for external use and improved with small pigmentation on the left eye-lid. Seven weeks after the onset of HZO, she suddenly developed aphasia and right hemiparesis. Cerebral angiogram showed narrowing on M 1 segment of the ipsilateral middle cerebral artery. The occlusion was seen on peripheral portion of the angular artery on the same side. In cerebrospinal fluid (CSF), cell count was slightly elevated, but concentration of protein and sugar were normal. Varicella-zoster titer was increased in both serum and CSF. She was treated with intravenous ACV (1500 mg/day) for 10 days. On the next day after the treatment, the cell count was normalized and on 18th day, varicella-zoster titer was decreased in CSF. Higher brain function improved and no relapses occurred. This is a first case of delayed cerebral infarction occurring in puerperium preceded by herpes zoster ophthalmicus in late pregnancy, as far as we searched. We should treat carefully pregnant or lactating patients with HZO, considering delayed cerebral infarction.
