We report a 39-year-old man with recurrent herpes simplex virus (HSV) encephalitis whose brain
MRI revealed bilateral high signal intensity of the hippocampus despite administration of intravenous
acyclovir for presumed herpes encephalitis. This case not only demonstrated unusual MRI findings
for recurrent HSV encephalitis, but it also revealed that HSV encephalitis can relapse despite intravenous
antiviral treatment. Therefore, close observation or sufficient duration of treatment is needed
for patients with HSV encephalitis.
