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.

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).

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.

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).
