Parsonage Turner syndrome caused by Staphylococcus aureus spondylodiscitis.

Parsonage Turner syndrome (otherwise known as PTS, neuralgic amyotrophy or acute brachial neuritis) is a rare, but clinically significant cause of atraumatic shoulder girdle pain and weakness. Diagnosis is primarily clinical and can be challenging due to its heterogeneous presentation. A case of PTS following systemic infection from Staphylococcus aureus spondylodiscitis is presented. Timely consideration of the diagnosis prevented unnecessary investigation and allowed effective rehabilitation. This is the first case of PTS preceded by S. aureus infection. PTS should be considered in those presenting with acute, atraumatic shoulder dysfunction after systemic infection. © BMJ Publishing Group Limited 2020. No commercial re-use.
