Figure 1. Manifestation of vaccine strain varicella zoster virus-induced central nervous system vasculopathy.
Axial diffusion weighted magnetic resonance image obtained after onset of neurological symptoms demonstrated scattered sites of acute ischemia involving the parasagittal cortices bilaterally and the left perirolandic cortex (panel A). Three-dimensional time of flight magnetic resonance angiographic image of the circle of Willis revealed multifocal stenotic anterior cerebral (short arrow), anterior communicating (dashed arrow), and middle cerebral (long arrows) arteries (panel B). Post-contrast T1W black blood arterial wall image illustrated avid enhancement and thickening of the distal supraclinoid internal carotid arterial walls bilaterally (panel C, arrows).
