71-year-old female patient with right shoulder pain. Question of rotator cuff tear. The exam is limited due to the patient's large body habitus and claustrophobia resulting in images that are degraded by motion artifact.ROTATOR CUFF: There is increased signal intensity within the anterior fibers of the supraspinatus tendon likely representing a full-thickness insertional tear measuring 1 cm in the AP dimension with minimal retraction. Increased signal intensity within the tendon more proximally indicates tendinosis. There is mild atrophy of the supraspinatus muscle. There are small foci of fluid signal intensity within the infraspinatus tendon along the myotendinous junction representing focal interstitial tears with equivocal extension to the bursal surface. There are also tiny interstitial undersurface tears of the infraspinatus tendon at its insertion, but we see no full-thickness tear. There is mild atrophy of the infraspinatus muscle. The teres minor muscle and tendon are intact. There is increased signal intensity in the subscapularis tendon indicating tendinosis with focal fluid signal intensity indicating interstitial tears as well as undersurface fraying. We see no full-thickness tear.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid in the subdeltoid/subacromial bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild to moderate osteoarthritis affects the glenohumeral joint. A small amount of fluid is noted in the joint, but no frank effusion. Evaluation of the labrum is limited due to motion artifact, however, there is increased signal intensity in the superior labrum indicating a tear. There is mild deformity of the anterior labrum likely representing degeneration.BICEPS TENDON: Increased signal intensity in the tendon of the long head of the biceps at its transition at the rotator cuff interval to the intertubercular groove indicates tendinosis. There also appears to be a longitudinal tear of the long head of the biceps tendon within the bicipital groove. Increased signal intensity within the bicipital groove on the fluid sensitive sequence suggests mild tenosynovitis.ADDITIONAL
1. Limited study due to patient body habitus and motion artifact showing rotator cuff tendinosis as well as a probable full-thickness tear of the anterior fibers of the supraspinatus tendon and partial thickness, largely intrasubstance, tears of the infraspinatus and subscapularis tendons.2. Osteoarthritis of the acromioclavicular and glenohumeral joints and other findings as described above.
