Herpes zoster is a localized disease characterized by unilateral pain with a vesicular eruption caused by the varicella zoster virus. In addition to sensory neurons, it may also affect motor neurons in 5 to 31% of cases. The skin lesions are classically limited to a single dermatome and bilateral involvement is rare, which has been referred to as herpes zoster duplex bilateralis. A 52-year-old male developed painful erythematous grouped papulovesicular eruptions on Rt. arm(Rt. C8 dermatome) twenty days ago. Eighteen days after the onset, same symptoms appeared along Lt. arm(Lt. C8 dermatome). Progressive motor weakness of Rt. arm and ptosis of Rt. eyelid were also observed. Histopathologic examination of the vesicle showed acantholytic multinulceated giant cells and partial ballooning degeneration in epidermis. The findings of C-spine MRI, motor nerve conduction study and electromyography were comprehensively compatible of Rt. brachial plexopathy. About 5 months after antiviral therapy, he demonstrated almost complete resolution of motor paralysis. Herein, we report a rare case of motor paralysis of Rt. arm following herpes zoster duplex bilateralis symmetricus.
