(A-D) Diffusion weighted imaging(DWI) showed multiple and small areas of acute infarction on the left basal ganglia, thalamus, and temporal lobe. (E,F) ADC image showed multiple and small areas of low signal areas on the left basal ganglia, thalamus, and temporal lobe.

Head MRI showed multiple small areas of acute infarction on the left basal ganglia, thalamus, and temporal lobe (Figures 1A-F).
High-resolution MRI (HR-MRI) examination at hospitalization. (A) Time of flight (TOF) magnetic resonance angiography (MRA) showed severe M1 stenosis in the left middle cerebral artery (MCA). (B) T1-weighted volume isotropic turbo spin-echo acquisition (T1W-VISTA) showed the location of the plaque and thickens the eccentric canal wall. T1W-VISTA also showed no significant enhancement on the plaque or surface, similar to the surrounding tissue signals, indicating no thrombosis on the surface of the plaque. (C) 3D-VISTA reconstruction was carried out at the maximal-lumen-narrowing site, and the rough shape of the patch was hand-drawn. HR-MRI examination after 24 months. (D) TOF MRA showed that the degree of lumen stenosis was significantly reduced. (E) T1W-VISTA showed that there were still some plaques on the tube wall, and the lumen was slightly narrow. (F) 3D-VISTA reconstruction showed the diameter of the tube was significantly larger.

HR-MRI examinations at hospitalization showed moderate to severe stenosis of the M1 section of the left middle cerebral artery (MCA; Figures 2A-C). The reexamination result of HR-MRI at 24 months was better, during which the lumen was slightly narrowed and the wall was slightly thickened in the same place (Figures 2D-F).
