A 62 year-old man, who was taking prednisolone for nephrotic syndrome, was diagnosed with herpes zoster of the trigeminal nerve and treated with oral valacyclovir. One month later, he reported pain from the right side of the head and vomiting. MRI revealed an acute infarction in the right frontal lobe and dissection of the internal carotid artery of the right cervix. Trauma or other potential triggers were not observed. In consideration of the preceding condition of varicella zoster virus infection, acyclovir was administered in addition to unfractionated heparin, but an intramural hematoma emerged in the left internal carotid artery. Furthermore, evidence showing progression of these lesions was found. On the fifth day, prednisolone was increased to 1 mg/kg/day, and progression of vascular lesions was not observed. This case may prove valuable because it suggests a relationship between cervical artery dissection and herpes zoster.
