Two Patients with Unusual Forms of Varicella–Zoster Virus Vasculopathy

Several months after having zoster on the sacrum, a 71-year-old man had a transient ischemic attack with occlusion of the right anterior cerebral artery. Six months after having zoster in the ophthalmic distribution, a 76-year-old woman had sudden loss of vision in the left eye. In both cases, the acute vascular events were caused by the varicella–zoster virus, and in both, the deficits resolved after intravenous treatment with acyclovir.
