Pre- and post-contrast MRI of the brain in a 45-year-old male patient with proven MELAS on muscle biopsy. GRD is observed in the right parietal cortex (arrows) on axial DWI (a) and ADC image (b). Associated gyral swelling and hyperintense signal (arrows) is seen on axial T2W (c) and coronal FLAIR image (d). No enhancement is seen in this region on post-contrast axial T1W image (e). Reconstructed maximum intensity projection MRA image of Circle of Willis (f) confirms no large vessel occlusion
