Pain and Weakness on Unilateral Upper Extremity Diagnosed as Brachial Plexopathy after Herpes Zoster Infection

Motor paralysis is a less common neurologic complication of herpes zoster. Until now, a few cases have been reported, and most of these cases showed brachial plexopathy involving one or two segments. We report a patient with pain and weakness on upper extremity diagnosed as brachial plexopathy after herpes zoster infection. An 88-year-old female patient complained not only tingling sense, pain, and swelling on right whole arm, but also weakness on this right upper extremity. On physical examination, weakness is seen in right shoulder abduction·shoulder flexion·elbow flexion·elbow extension· wrist extension (grade 4), finger flexion·finger abduction·finger extension·finger DIP flexion (grade 3). In electrodiagnostic study and magnetic resonance imaging study, she was diagnosed as the brachial plexopathy, whole branch involved. This is the only case of post-herpetic brachial plexopathy involving whole branch in domestic.
