MRA
QUIZ 3: Shoulder Imaging
 Parsonage Turner syndrome is an acute idiopathic brachial
neuritis
 Diagnosis is made with a combination of history, EMG
(which demonstrates denervation changes, especially of the
suprascapular nerve) and imaging
 the most frequently involved muscles are supraspinatus and
infraspinatus (innervated by suprascapular nerve) followed
by deltoid (innervated by axillary nerve)
