Atypical Presentation of Parsonage-Turner Syndrome

Parsonage-Turner syndrome, also known as idiopathic brachial neuritis, is a multifocal, complex inflammatory disorder of the brachial plexus. It is an under-recognized diagnosis that requires increased vigilance to diagnose. We present a case of an abnormal presentation of Parsonage-Turner syndrome 10 weeks after a rotator cuff tear repair surgery. To diagnose this condition, other potential causes should be ruled out effectively with modalities such as magnetic resonance imaging (MRI) of the cervical spine and shoulder, electromyography (EMG), or recent history of inciting events.
