Cervical (C2) herpes zoster infection followed by pontine infarction.

This article reports a man who had herpes varicella zoster cervicalis with delayed stroke in the posterior circulation. Empiric treatment was acyclovir, methylprednisolone, and aspirin. Pontine infarction involving migration of the virus via cervicovascular innervation from C2 dorsal root ganglia to the vertebrobasilar circulation with attendant angiitis/angiopathy and thrombosis is proposed.
