This case highlights the atypical presentation of acute brachial neuritis or Parsonage Turner Syndrome, which usually presents as sudden onset of severe shoulder pain with loss of function. A 36-year-old squash player presented with a history of persistent left shoulder pain of insidious onset. On examination, he was found to have significant wasting, as well as weakness, on testing of the supraspinatus and infraspinatus muscles. Electromyography (EMG) confirmed denervation and showed some evidence of re-innervation of both infraspinatus and supraspinatus. Magnetic resonance imaging (MRI) showed no compressive lesion, but evidence of muscle denervation.
