Figure 16 (A-D): Viral encephalitis. A 13-year-old male came with headache, fever, and disorientation for 4 days. MRI shows bilateral symmetrical high signal intensity in the basal ganglia, internal capsule (double arrows in A-C), and splenium of corpus callosum (single arrows in A-C) on FLAIR image (A). These areas show restricted diffusion on diffusion-weighted image (B) and ADC maps (C). On follow-up scan 2 weeks later, FLAIR image (D) shows reversal of abnormal signal in the splenium (single arrow) and left putamen (double arrow)
