Imaging of Herpesvirus Infections of the CNS

Abstract

OBJECTIVE. Herpesviridae are a family of DNA viruses remarkable for their ability to both promote acute infection and enter a latent phase with potential of reactivation. Herpes infections are ubiquitous throughout the human life span, regardless of the degree of immunocompetence. CONCLUSION. We review the virology and clinical manifestations of each herpesvirus, with emphasis on recent advances in knowledge and characteristic neuroimaging findings important for diagnosis and appropriate clinical management.
