Female 62 years old with right shoulder pain. Evaluate rotator cuff. ROTATOR CUFF: There is mild tendinosis of the supraspinatus tendon and perhaps mild undersurface fraying. In addition, there is a tiny cyst at the insertion of the supraspinatus tendon on the humerus but we see no full-thickness supraspinatus tendon tear. There is mild fatty atrophy of the supraspinatus muscle belly proximally. There is longitudinal, predominantly interstitial, tearing of the distal infraspinatus tendon perhaps with surface extension but no tendon retraction. There is edema in the underlying humeral head. The infraspinatus muscle appears normal. The teres minor and subscapularis muscles and tendons appear intact although there is a small cyst in the humeral head underlying the teres minor tendon insertion.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is trace fluid in the subacromial bursa of doubtful clinical significance.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is normal. There is a small amount of fluid within the joint but no effusion. Linear intermediate signal in the posterior superior labrum may represent a tear. Fluid signal intensity more anteriorly could represent additional tearing or simply a normal variant sublabral recess. The inferior labrum appears normal.BICEPS TENDON: The long head of the biceps is normal in appearance. ADDITIONAL
1.Partial thickness rotator cuff tearing as described above.2.Osteoarthritis of the acromioclavicular joint.3.Edema at the origin of the deltoid muscle posteriorly may represent a strain or enthesopathic inflammation.4.Other findings as above.
