Early ischemic changes on noncontrast head CT scan

Early ischemic changes on noncontrast head CT scan
Findings of EIC in a 59-year-old man who presented with acute left hemiparesis. (A and B) NCCT 3.5 hours after symptom onset shows hypodensity and cortical swelling with sulcal effacement. There is loss of gray-white matter differentiation in the right frontal operculum, right temporal operculum, right insular cortex, and right frontoparietal lobes (arrowheads).
CT: computed tomography; EIC: early ischemic changes; NCCT: noncontrast-enhanced computed tomography.
