Fluid attenuated inversion recovery (FLAIR) showed cord sign and dot sign consistent with those of the superficial Sylvian vein. Axial sections (A), sagittal sections (C), and coronal sections (D). Echo-planar T2* susceptibility-weighted imaging also showed a restiform low-intensity lesion that coincided with the high-intensity lesion in FLAIR (B).

Fluid-attenuated inversion recovery (FLAIR) showed a long restiform high-intensity lesion on the surface of the sylvian fissure (Fig. 1A, C, D) that started in the left sylvian fissure around the supramarginal gyrus, followed the surface of the sylvian fissure, and ended at the sphenoid ridge. T2* susceptibility-weighted imaging (T2*SW) (Fig. 1B). There was no obvious signal change in the parenchyma suggestive of edema, infarction, or hemorrhage.
