Transient intrathecal IgG synthesis in herpes zoster myelitis: 2 case reports.

ABSTRACT

Alterations in cerebrospinal fluid in 2 cases of viral myelopathy associated with herpes zoster infection are reported. Viral myelopathy is a rare complication of herpes zoster. Quantitatively there was a slight increase in IgG production and oligoclonal IgG bands were detected by isoelectric focusing. These parameters returned to normal after 1 year suggesting a transient involvement of the central nervous system.
