Figure 8:

(A) A patient with a diagnosis of varicella zoster vasculitis shows multiple segments of avid wall thickening and enhancement along the course of the bilateral anterior cerebral arteries (arrows) including the pericallosal artery (arrowhead) on postcontrast T1w VWI. (B) Coronal plane of the enhancing pericallosal artery segment shows both concentric wall enhancement as well as enhancement extending beyond the vessel wall borders, characteristic of perivascular enhancement (arrowhead). (C–D) After 2 months of treatment with acyclovir, there was improvement in the degree of vessel wall and perivascular enhancement.
