a Diffusion weighted imaging (DWI) in the first 24 h after admission: acute infarct in the right basal ganglia in one acute ischemic stroke patient with a National Institutes of Health Stroke Scale (NIHSS) score of 6 at admission. b Magnetic resonance angiography: occlusion in the right middle cerebral artery (MCA). c Susceptibility weighted imaging: asymmetrically prominent cortical vein sign in the right MCA territory (arrow). d Repeat DWI after early neurological deterioration (END), (Day 3 and the NIHSS score increased to 14): enlargement of the infarction
