We report the case of a 55-year-old man presenting pseudopsychiatric behavior disorders of subacute-onset. MRI showed a FLAIR (fluid-attenuated inversion recovery) hyperintensity in the left hippocampus. The diagnosis of limbic encephalitis was raised, and the patient was referred for an 18F-FDG PET/CT. PET/CT depicted an increased uptake of the left mesiotemporal structures and also an increased uptake of both cerebellum and striatal areas. This pattern was compatible with an anti-leucine-rich glioma-inactivated 1 antibody encephalitis that was later confirmed.
我们报告了一例 55 岁男性出现亚急性起病的假性精神病性行为障碍。MRI 显示左侧海马体 FLAIR（液体衰减反转恢复）高信号。诊断为边缘性脑炎，并将患者转介进行 18F-FDG PET/CT 检查。PET/CT 显示左侧颞叶结构摄取增加，同时小脑和纹状体区域摄取增加。这种模式与抗亮氨酸丰富型胶质瘤失活 1 抗体脑炎相符，后来得到了证实。
