CDR2 and Atrophy: Only one patient displayed typical findings suggestive of limbic encephalitis with a FLAIR-intense signal in the limbic system (Figure 2A,B) and another increased T2 signal in the basal ganglia (anti-CV2 and Yo encephalitis), whereas others displayed more atypical findings, such as cerebellar vermal atrophy (anti-CV2 encephalitis, Figure 2C), cortical and hippocampal atrophy (anti-GAD encephalitis, Figure 2D–F), generalized atrophy (anti-MA2, n = 1; anti-Yo, n = 1; anti-caspr−2, n = 1), hippocampal asymmetry (anti-NMDAR, n = 1).
