Small acute left MCA infarct

Small acute left MCA infarct, with severe chronic small vessel white matter ischemic disease. The CT reveals only severe, bilateral, chronic ischemic disease (with abnormal low attenuation), which is also well seen on the FLAIR scan from the MR exam (with abnormal high signal intensity). The diffusion weighted scan enables detection of a small acute MCA infarct (with abnormal high signal intensity on DWI), which involves both the cortex and underlying white matter of the corona radiata.
