MRI of the brain in a 26-year-old female patient brought unconscious following valproate overdose. Symmetric GRD is seen in the cingulate gyri (arrows) on axial DWI (a) and ADC image (b). GRD is also seen in the insular cortices (arrows) on axial DWI (d) and ADC image (e). Coronal FLAIR images (c, f) reveal hyperintense cortical swelling in these regions, along with similar signal changes in bilateral mesial temporal lobes. Laboratory tests confirmed the diagnosis of hyperammonaemia
