Abstract

Purpose:To describe the clinical features of herpes zoster that can be easily misdiagnosed as cervical or lumbar radiculopathy.
Material and Methods :We retrospectively reviewed the medical records and diagnostic studies of 7 patients with herpes zoster-related arm or leg pain.
Results: Except one immunocompromised patient with suspected postherpetic neuralgia or sequelae of herpetic myelitis, the other 6 patients with herpes zoster complained of very severe initial pain of sudden onset. Three patients did not show skin lesions on initial examination, and 2 of 5 patients with an MRI of the cervical or lumbar spine had findings consistent with their arm or leg pain and may have been confused with radiculopathy. Conservative treatment, including antiviral agents, improved the symptoms of all patients except the immunocompromised one. Selective nerve root blocks of the corresponding dermatomes were performed in 5 patients and extremity pain decreased over 50% in 4 of them.
Conclusion: Herpes zoster can be confused with radiculopathy in patients with arm or leg pain if the typical skin lesions have not been developed. Unnecessary treatments including surgery should be avoided by early, correct diagnosis through prudent history taking and physical examination.
