Female, 75 years old. Right shoulder pain and weakness ROTATOR CUFF: There is moderate to severe thinning of the supraspinous tendon compatible with chronic attritional tearing that has progressed compared to the prior study. Increased signal intensity replacing the distal fibers of the supraspinatus tendon likely represents a combination of tendinosis and tearing. There may be a focal full-thickness tear affecting the anterior fibers of the supraspinatus tendon at their insertion, but this is equivocal. There is mild fatty atrophy of the supraspinatus muscle. Mild edema type signal within the muscle on fat suppressed T2 sequences may reflect denervation injury or a strain. There is thickening and increased signal intensity of the infraspinatus tendon representing tendinosis that has progressed from the prior study. There are also cystic structures along the myotendinous junction more proximally. Mild to moderate fatty atrophy of the infraspinatus muscle appears to have progressed from the prior study. There is also edema type signal within the infraspinatus muscle on fat suppressed T2 sequences which may reflect denervation injury or strain. The teres minor tendon and muscle are intact. There is increased signal intensity within the subscapularis tendon involving the majority of the thickness of the tendon with sparing of the bursal surface fibers indicating a high-grade partial-thickness tear. There also appears to be incomplete insertional tearing of the subscapularis tendon. Subscapularis tendon tearing has progressed when compared to the prior study. There is mild atrophy of the subscapularis muscle.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthritis affects the glenohumeral joint. There is a small amount of fluid in the joint but no large effusion. Given the limitations of a nonarthrogram study, the glenoid labrum appears normal for age.BICEPS TENDON: There is medial dislocation of the biceps tendon from the bicipital groove which is new when compared to the prior study.
1.Progression of partial thickness tearing of the supraspinatus, infraspinatus, and subscapularis tendons with equivocal focal full-thickness tear of the anterior fibers of the supraspinatus tendon at their insertion.2.Osteoarthritis and other findings as above, including medial dislocation of the biceps tendon.
