Axial magnetic resonance imaging (MRI) findings of patient 1 and patient 2 in fluid-attenuated inversion recovery (FLAIR) sequence. a Patient 1, a 35-year-old Chinese female, was diagnosed with typical limbic encephalitis, and MRI showed increased FLAIR signals of the right medial temporal lobe, including the amygdala and hippocampus. b–d Patient 2, a 35-year-old male, was characterized by stiff-person syndrome, cerebellar ataxia and intractable epilepsy. MRI indicated postoperative changes in the left frontal lobe, volume reduction in the left temporal lobe and hippocampus, and encephalatrophy, especially in the bilateral cerebellum
