Parsonage
Turner syndrome
is
an acute idiopathic brachial neuritisDiagnosis is made with a combination of history, EMG (which demonstrates denervation changes, especially of the
suprascapular
nerve) and imagingthe most frequently involved muscles are supraspinatus and infraspinatus (innervated by suprascapular
nerve) followed by deltoid (innervated by axillary nerve)
