Abstract

Abstract An 83‐year‐old man developed acute ischemic stroke. Brain magnetic resonance imaging (MRI) showed ischemic stroke in the left parietal lobe gyri, but fluid‐attenuated inversion recovery (FLAIR) showed hyperintensity in the contralateral right temporal‐occipital lobe sulci. Follow‐up FLAIR image showed the gradual disappearance of the sulcal hyperintensity in the sulci and changed to linear serpiginous structures. This is a unique stroke case showing transitioned FLAIR findings suggesting that the sulcal hyperintensity findings are more severe and an earlier ischemic condition than the linear serpiginous structures.
