Figure 2: A 61-year-old male with a history of hypertension, diabetes, coronary artery disease woke up with left-sided weakness and numbness. (a) Diffusion-weighted imaging sequence showing acute to subacute infarct in the right middle cerebral artery territory involving caudate head, basal ganglia, and parietal lobe. (b and c) Fluid-attenuated inversion recovery sequence shows subtle hyperintensity suggesting diffusion weighted imaging-fluid attenuated inversion recovery mismatch, distal vascular hyperintensities secondary to slow flow and absence of flow void in proximal, middle cerebral artery segment. (d) Digital subtraction angiogram demonstrating critical stenosis of proximal right internal carotid artery with tandem occlusion of supraclinoid segment. (e) balloon angioplasty of proximal stenosis (f) final evolution of right MCA territory infarct
