Post-transplant acute limbic encephalitis caused by HHV-6: Initial magnetic resonance imaging findings with days from symptom onset indicated

Axial FLAIR (top) and diffusion-weighted (bottom) sequences demonstrate limbic system involvement, including the uncus, amygdala, and anterior hippocampus in all patients. For Patient 6, only coronal FLAIR images from day 2 were available. An axial FLAIR image from day 6, with findings similar to those on day 2, is shown. The left side of each image corresponds to the right side of the brain.
