Figure 1.
Representative images of abnormal cerebral glucose metabolism in individual patients with N-methyl-D-aspartate receptor antibody encephalitis detected by 18F-fluoro-2-deoxy-d-glucose positron emission tomography. Patients with mild or moderate clinical severity (patients #1 and #2; mRS ≤3) show temporomesial hyperintensities, whereas more widespread frontal and temporal hyperintensities and occipital hypointensities in patients with severe disease (patients #4 and #6; mRS >3) are observed. Representative sections are shown (all images available in online supplementary figure 1). Significant hyper- and hypometabolism is colour/gray-scale coded as depicted in the legend. mRS, modified Rankin Scale.
