Representative cases of patients with different ASPECTS subregions involvement and clinical outcomes. Case A: A 73-year-old man with left MCA occlusion on TOF-MRA. The baseline NIHSS score was 12. Posttreatment MR-DWI showed the infarct lesion involving the left insula, M1, M4, and M5 regions with an ASPECTS of 6. This patient received intravenous thrombolysis therapy yet suffered moderately severe disability with a 3-month mRS score of 4. Case B: A 73-year-old woman with left MCA severe stenosis and baseline NIHSS score of 9. The infarct lesion affected the left insula, M3, M5, and M6 (ASPECTS score = 6). This patient received medical therapy and presented slight poststroke disability with a 3-month mRS score of 2. Case C: A 69-year-old man with right MCA occlusion and baseline NIHSS score of 8. The infarct lesion involved the right insula, M1, M2, M4, and M5 (ASPECTS score = 5). This patient presented slight poststroke disability with an mRS score of 2 at 3 months. Case D: A 53-year-old man with right MCA occlusion and baseline NIHSS score of 4. Posttreatment DWI showed the infarct lesion involving the right insula, M2, M3, and M6 (ASPECTS score = 6). This patient presented moderate disability with a 3-month mRS score of 3. MCA: middle cerebral artery; TOF-MRA: time-of-flight MR angiography; NIHSS: National Institute of Health Stroke Scale; mRS: modified Rankin Scale; ASPECTS: Alberta Stroke Program Early CT Score; MR: magnetic resonance; DWI: diffusion-weighted imaging.
