A Fatal Case of Herpes Simplex Encephalitis with Two False-Negative Polymerase Chain Reactions [PDF]

Case Reports in Neurology, 2018
An 88-year-old man presented with a 1-month history of altered mental status and seizures. His electrographic and imaging findings were suggestive of herpes simplex encephalitis (HSE), for which he was empirically treated with acyclovir.
