Spectrum of imaging findings in immunocompromised patients with HHV-6 infection.

Abstract

The aim of this article is to review systemic manifestations of human herpes virus 6 (HHV-6) associated diseases in immunocompromised patients. The spectrum of HHV-6 associated disorders is broad, but radiologists are frequently not familiar with these disorders. In the clinical setting of acute infection in an immunocompromised patient, the presence of one of these findings (e.g., limbic encephalitis; atypical interstitial pneumonia; pericarditis or myocarditis; or, less commonly, gastrointestinal or hepatobiliary disorders) should raise the suspicion of a possible HHV-6 related complication.
