Figure 2.

A 46‐year‐old male patient presented with right ischemic stroke. A, Axial diffusion‐weighted imaging detects a slightly high signal intensity lesion (white arrow) in the right centrum ovale. B, Time‐of‐flight magnetic resonance angiography shows a severe stenosis (red arrow) in the right middle cerebral artery (MCA) and a mild stenosis (white arrow) in the left MCA. C, Curved planar reconstruction image, based on the precontrast whole‐brain vessel wall imaging, shows a plaque with HST1 (red arrow) in the culprit plaque of right MCA‐M1. Plaques without high signal on T1‐weighted images are detected in the probably culprit plaque of the right MCA M2 segment (gold arrow) and the nonculprit plaque of the left MCA M1 segment (white arrow).
