Abstract
An 81-year-old man was admitted to our hospital with left hemiplegia after treatment for herpes zoster of the first branch of the right trigeminal nerve. CSF examination revealed an elevated varicella-zoster virus (VZV) antibody index. Brain MRI showed cerebral infarction in the right middle cerebral artery (MCA) territory and vessel wall thickening and enhancing effects at the ipsilateral MCA. Despite the standard treatment, the MCA stenosis progressed with recurrent infarcts. Percutaneous cerebral angioplasty was performed to the distal portion of the right MCA without deterioration. This case can provide a treatment option for refractory progressive VZV vasculopathy.
