Parsonage-Turner syndrome following COVID-19 vaccination and review of the literature

Abstract

Background: Parsonage-Turner syndrome (PTS) is a rare brachial plexopathy characterized by self-limiting shoulder girdle and upper arm pain followed by the upper extremity weakness and sensory changes. While the etiology is not well-understood, the most common cause of PTS is thought to be postviral. There are at least nine reports, to the best of our knowledge, of PTS associated with COVID-19 infection and nine reports associated with COVID-19 vaccination. Case Description: Here, we present a case of PTS after COVID-19 vaccination in a 64-year-old male and a review of the current literature. Conclusion: PTS can occur post-COVID-19 vaccination and should be on the differential diagnosis when patient continues to experience shoulder pain and develops weakness or sensory changes in the extremity.
