A case of varicella-zoster myelopathy
2009
Introduction - Early diagnosis of neurological complications of varicellazoster virus (VZV) is important because of its treatability. We performed polymerase chain reaction (PCR) to detect VZV-DNA from the cerebrospinal fluid (CSF) of a patient with myelopathy. Patient & methods - A 69-year-old man developed sensory disturbances in the lower extremities and bladder-bowel disturbances, followed by cutaneous zoster on his left arm. Polymerase chain reaction was applied to identify the viral DNA in CSF. Results - The increased antibody index of VZV and herpes simplex virus (HSV) in the CSF suggested intrathecal synthesis of IgG antibodies to these viruses. VZV-DNA was detected in the CSF by nested PCR, but neither HSV-1 nor HSV-2 DNA was detected in CSF. He was successfully treated with acyclovir and prednisolone. Conclusion - PCR may be a useful tool for the diagnosis of VZV myelopathy.
