S upraScapular neuropathy has been recognized as a potential cause of shoulder pain and weakness. 2,5 Along its course to innervate the supraspinatus muscle, infraspinatus muscle, and glenohumeral joint, the suprascapular nerve (SSN) passes through 2 potential points of impingement: the suprascapular notch and the spinoglenoid notch. 41 Paralabral (extraneural) cysts are globular masses filled with mucoid material that emanate from the glenohumeral joint and can occasionally extrinsically
