Human herpesvirus 6 meningoradiculitis treated with intravenous immunoglobulin and valganciclovir.

Human herpesvirus 6 (HHV-6) is being increasingly associated with multiple neurological conditions. The authors report the case of a 26-year-old man with subacute meningoradiculitis initially treated with intravenous immunoglobulin. The cerebrospinal fluid (CSF) showed pleocytosis and polymerase chain reaction (PCR) was positive for HHV-6 type B DNA in the CSF and peripheral blood. He was subsequently treated with valganciclovir with near resolution of his symptoms.
