18F-FDG-PET characteristics of LGI1 AE patients in different clinical phases. FDG-PET hypermetabolism was specifically located in the BG and MTL, whether it was in the acute phase or chronic phase, and there is no statistical metabolic change between acute and chronic phases for BG and MTL. LGI1, leucine-rich glioma-inactivated 1; AE, autoimmune encephalitis; 18F-FDG-PET, 18F-fluoro-2-deoxy-d-glucose positron emission tomography; BG, basal ganglia; MTL, medial temporal lobe.
