Magnetic resonance angiography (MRA) in patient 1 (A) showed occlusion of the left vertebral artery (VA) and intracranial diffuse atherosclerosis, especially in the right VA, the left MCA, and the right posterior cerebral artery (PCA). The MRA in patient 2 (B) showed a lack of circulation in the left ICA and MCA, with intracranial atherosclerosis predominantly affecting the right MCA and PCA.

MRI scan revealed multiple acute ischaemic lesions in the midbrain, pons, and occipital cortex. MR angiography (MRA) showed occlusion of the vertebral artery and significant intracranial atherosclerosis (Fig. 1A).

MRI scan revealed multiple ischaemic lesions in the right frontal and parietal cortex. MR angiography showed ICA dissection and MCA stenosis of more than 50% (Fig. 2A and B).
