A case of herpes zoster associated encephalitis with rapid response to acyclovir

Abstract
Summary: A case of herpes zoster encephalitis which responded very rapidly to acyclovir is presented. The differential serum: cerebrospinal fluid antibody response was followed and its value in making the diagnosis is discussed. The penetration of acyclovir into the cerebrospinal fluid was measured, and found to be in agreement with predicted values.
