61-year-old male with shoulder pain and symptoms of rotator cuff tear. ROTATOR CUFF: There is a partial-thickness undersurface tear of the anterior fibers of the infraspinatus tendon at the level of its insertion on the greater tuberosity, measuring approximately 6 mm in the AP dimension, involving less than 50% of the tendon width. There is no significant retraction. The supraspinatus tendon and muscle appear intact. The teres minor and subscapularis muscles and tendons appear intact.SUPRASPINATUS OUTLET: Moderate degenerative changes affect the acromioclavicular joint. There is a small amount of fluid within the subacromial subdeltoid bursa which may reflect a mild bursitis.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. No articular cartilage defects are identified. Although this examination was not protocoled for evaluation of the glenoid labrum, there is heterogeneity and increased signal abnormality affecting the anterior inferior glenoid labrum suggestive of degenerative tearing.BICEPS TENDON: There is a small amount of fluid within the tendon sheath of the long head of the biceps which may reflect fluid extension from the glenohumeral joint versus a mild tenosynovitis.ADDITIONAL
Small partial thickness tear of the infraspinatus tendon without evidence of a full-thickness rotator cuff tear. Other findings as described above.
