Finding the Cause of Psychosis: A Challenging Case of Anti-NMDAR Encephalitis

Figure 2

Axial magnetic resonance images (MRIs) one and a half weeks after treatment with immunoglobulin and methylprednisolone demonstrating gyriform swelling of the temporal lobes (a), especially medially, best seen on flair sequences (a, c, d). There is a faint bright signal intensity observed in the bilateral thalami and basal ganglia (c). Vague cortical brightness is also seen. There is no evidence of abnormal contrast enhancement (b). Compared to the earlier study, the degree of bright signal intensity is decreased, though swelling remains. These findings, with cortical, thalamic, and basal ganglia involvement, are typically seen in encephalitis.
