Development of Acute Onset Upper Extremity Motor Paresis Following Outbreak of Herpes Zoster Rash: A Case Report

Video Transcription

Video Summary

This video explores the case of a 60-year-old female who developed motor paresis following a herpes zoster infection. Motor paresis is a rare complication without a fully understood mechanism. The patient experienced right upper extremity pain followed by a shingles rash and then developed acute weakness in her right upper extremity. She underwent physical therapy and regained near full function within three months. The diagnostic workup showed T2 hyperintensity in the affected muscles on MRI and needle EMG abnormalities in the deltoid and infraspinatus. Possible diagnoses discussed include brachial neuritis, mononeuritis multiplex, and segmental zoster paresis. Electrodiagnostic testing was useful in prognosis, and the patient had a good recovery.
