Abstract

Herpes simplex encephalitis (HSE) is the most common type of viral encephalitis and a fourteen day administration of acyclovir is well-known as the treatment of choice for HSE. Occasionally HSE relapses, but rarely with acyclovir treatment. We report a case of relapsing HSE after treatment with acyclovir for 14 days. Our case suggests that patients with progressive high signal intensities in diffusion-weighted brain MRIs might need longer antiviral therapy over 14 days for preventing the relapse of herpes simplex encephalitis.
