Subacute encephalitis caused by herpes simplex virus

: The authors present a case of herpes-simplex encephalitis in a 58-year-old woman. The disease had a biphasic course and lasted 87 days. The clinical picture, laboratory data and the pathologic-anatomical changes of the disease are discussed. The authors also emphasize the importance of the encephalitic process in the brain stem, which can make the clinical picture even more complicated because of the appearance of respiratory disturbances.
