Figure 1: (A) AxT1 MRI showing volume loss of rt. amygdala and distention of the rt. temp. horn. (B) AxT1: mild generalized cerebral volume loss, no lobar predilection. (C) CorT2 FLAIR with hyperintensity of rt. hippocampus, amygdala. (D) Area CA4 of hippocampus: extensive neuronal loss and gliosis. (E) Focal perivascular lymphoid infiltrate in the temporal white matter. (F) Blood vessels in white matter with thickened vessel walls, perivascular clearing and hemosiderin. (G) IHC for GFAP on a section from temporal cortex showing marked gliosis. (H) CD3: occasional perivascular T-cells. (I) CD4 in cortex demonstrating activated microglia.
