FIG 1. Scarring of the left superior frontal gyrus. Axial 5-mm-thick (a–c) and coronal 3-mm-thick (d) FLAIR fast spin-echo images show an atrophic and hyperintense lesion in the right superior frontal gyrus (solid-head arrows in a–d). Note also a tiny increase in signal intensity and the atrophy in the depth of the right frontal superior sulcus (open-head arrows in a, c, and d)
