Widespread neurological disorders following herpes zoster are rare. These include radiculopathy, myelitis, contralateral hemiparesis, encephalitis and postherpetic neuralgia. Herpes zoster can be easily diagnosed by the appearance of the vesicular eruption following a dermatomal distribution, and the associated radiculopathy can be confirmed by electromyography. We present clinical symptoms, signs and electrodiagnostic findings of two cases of radiculopathy related to herpes zoster infection.
