A 57-year-old female patient, diabetic and hypertensive, presented with dysarthria. NIHSS on admission was 7 a axial T2 b axial diffusion WIs (b1000) show right fronto-parietal area of high signal and restricted diffusion in keeping with acute infarct. c Coronal FA color-coded map overlaid over coronal FLAIR image with fiber tractography of the CST that appear preserved. d Axial FA color-coded map overlaid over axial FLAIR image with tractography of the acurate fasciculus. e Sagittal FA color-coded map overlaid over sagittal FLAIR image with tractography of the right arcuate fasciculus. f Sagittal FA color-coded map with tractography of the left arcuate fasciculus. Note the disrupted right arcuate fasciculus (green) compared to the left one (pink). FA value at the site of infarct (0.3) compared to the contralateral normal side (0.4). The patient shows mild clinical improvement with residual speech difficulties. NIHSS after 3 months was 5
