Abstract
Introduction: A 34-year-old man presented with herpes simplex encephalitis (HSE), with magnetic resonance imaging (MRI) showing dense foci of restricted diffusion in the temporal lobe.
Case Report: With treatment and clinical improvement, follow-up MRI done 8 days later showed complete resolution of the restricted diffusion abnormalities, whereas other MRI sequences suggested interval progression.
Discussion: Restricted diffusion abnormalities on MRI in patients with HSE may be more sensitive to and correlate better with disease activity in HSE.
