A case of ischemic stroke secondary to varicella-zoster virus meningoencephalitis.

Varicella-zoster virus (VZV) lurks in cranial nerves and other brain ganglias after infection. Because middle cerebral artery (MCA) receives the ipsilateral trigeminal ganglia afferent innervations, the reactivated VZV infects the adventitia and intima of cerebral artery wall probably through this way and causes vascular inflammation, finally resulting in artery remodeling, vessel occlusion, and ischemia. In fact, there is a growing clinical recognition that there is an association between VZV reactivation and subsequent stroke. Here, we showed a case of ischemic stroke secondary to varicella-zoster virus meningoencephalitis and reviewed the literature to emphasize the importance of VZV-associated vasculopathy.
