61-year-old male with shoulder pain. Rule out rotator cuff tear. ROTATOR CUFF: There is thickening and increased signal abnormality within the supraspinatus tendon consistent with moderate tendinosis. There is increased fluid signal abnormality within the supraspinatus at the level of the myotendinous junction consistent with interstitial and partial thickness undersurface tearing. There is also increased fluid signal abnormality within the posterior fibers of the supraspinatus tendon just proximal to the level of its insertion on the greater tuberosity consistent with interstitial tearing (image 12; series 701). The supraspinatus muscle appears intact. The infraspinatus muscle and tendon appear intact. The teres minor and subscapularis muscle and tendons appear intact.SUPRASPINATUS OUTLET: There is fluid within the subacromial subdeltoid bursa and acromioclavicular joint. Moderate degenerative changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Moderate to severe degenerative changes affect the glenohumeral joint including joint space narrowing and osteophyte formation. Although this examination was not protocoled for evaluation of the glenoid labrum, there is extensive increased signal abnormality within the superior labrum which extends to involve the biceps anchor, consistent with degenerative tearing of the labrum. Again seen is a 1 cm ossicle along the anterior-inferior margin of the glenoid which may reflect prior remote trauma.BICEPS TENDON: There is a small amount of fluid within the tendon sheath of the long head of the biceps which may represent fluid extension from the glenohumeral joint versus tenosynovitis. There is thickening and signal abnormality of the long head of the biceps tendon consistent with mild to moderate tendinosis.ADDITIONAL
1. Rotator cuff tendinosis and interstitial tearing of the supraspinatus, without evidence of a full-thickness rotator cuff tear.2. Findings consistent with subacromial bursitis.3. Degenerative changes and other findings, as described above.
