case_images: MRI, DSA and HR MRI findings of Case 1. (A) MRI diffusion weighted image shows a hypersensitive lesion on right putamen with rostral extension to the corona radiates. (B) Digital angiography of the right MCA shows normal. (C) High-resolution MRI of the MCA demonstrates an atherosclerotic plaque (arrow) on the frontal wall of the right proximal MCA.

case_images: Brain MRI showed an acute infarct on right putamen with rostral extension to the corona radiates (Figure 1A). Digital angiography of cerebral vascular showed no significant abnormal (Figure 1B). 3-T high-resolution MRI of bilateral MCA demonstrated an atherosclerotic plaque on the ventral wall of the right proximal MCA causing the vessel lumen irregular (Figure 1C). Medical management then switched to a combination of aspirin (200 mg daily), clopidogrel (75 mg daily) and statin (atorvastatin calcium 20 mg daily).

case_images: MRI, MRA and HR MRI findings of Case 2. (A) MRI diffusion weighted image shows a hypersensitive lesion on posterior limb of internal capsular. (B) MR angiography of the MCA is normal. (C) High-resolution MRI of MCA indicates the presence of an atherosclerotic plaque on the frontal wall of the right proximal MCA.

case_images: Brain MRI demonstrated an acute right-sided infarct on posterior limb of internal capsular (Figure 2A). Brain MRA showed no significant abnormalities (Figure 2B). High-resolution MRI of MCA indicated the presence of an atherosclerotic plaque on the ventral wall of the right proximal MCA (Figure 2C).
