    Abstract

    Varicella zoster virus (VZV) causes the common childhood isease chickenpox (varicella), or upon reactivation, the dermatomal vesiculopustular eruption seen in shingles (herpes zoster). The clinical course of herpes zoster in immunocompromised patients is often recurrent, protracted and multidermatomal, and it can result in myelitis, meningoencephalitis, and cerebral or small-vessel vasculopathic or vasculitic changes. Commonly, the vesicular rash settles with aciclovir therapy and does not involve motor neuropathy. We report a 63-year-old man with a prolonged, multidermatomal, nonvesicular rash, and limb paresis secondary to brachioplexitis. PCR for VZV was positive, and the histological results were consistent with granulomatous vasculopathy. Prolonged treatment with valaciclovir was required to resolve the eruption and help improve the patient's motor function. We discuss the problems faced in clinical decision-making about immunosuppressive treatment of granulomatous vasculopathy and motor neuropathy, when any increase in immunosuppressive therapy may increase the likelihood of central nervous system complications.
