50-year-old female with shoulder pain. ROTATOR CUFF: There is a full-thickness insertional tear of the supraspinatus with minimal retraction measuring approximately 13 mm in the AP dimension. There is mild edema extending along the superficial fibers of the supraspinatus muscle suggesting that this may represent an acute tear. There is also thickening and increased signal intensity within the remainder of the supraspinatus tendon indicating moderate tendinosis. There are subchondral cysts within the underlying greater tuberosity. There is minimal fatty infiltration along the myotendinous junction. There is thickening and increased signal intensity within the infraspinatus indicating moderate tendinosis, but we see no discrete tear. There is minimal fatty infiltration along the myotendinous junction, otherwise the infraspinatus muscle appears normal. There may be a couple of tiny interstitial tears of the distal subscapularis tendon, but otherwise the subscapularis muscle and tendon appear normal. The teres minor muscle and tendon appear intact.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint with osteophytes that result in mild impression upon the superior fibers of the supraspinatus. There is a small amount of fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. Minimal osteoarthritis affects the glenohumeral joint. There is a small amount of fluid within the joint with no frank effusion.BICEPS TENDON: There is increased signal intensity within the tendon of the long head of the biceps as it enters the bicipital groove from the rotator interval suggestive of a partial thickness tear, although this may be of no current clinical significance as there is minimal, if any, fluid within the tendon sheath. ADDITIONAL
1. Full-thickness but minimally retracted tear of the supraspinatus with additional rotator cuff tendinosis as described above.2. Moderate osteoarthritis of the acromioclavicular joint.3. Findings suggesting a partial thickness tear of the long head of the biceps tendon, although this may not be of any current clinical significance.
