Left shoulder pain. Rotator cuff tear? ROTATOR CUFF: There is a full-thickness, near-complete tear of the supraspinatus tendon from its insertion on the greater tuberosity; I suspect that a small portion of degenerated tendon anteriorly extends to the tuberosity. There is up to 1 cm of retraction of the torn tendon. The tear measures approximately 2 cm in AP dimension, involving the infraspinatus tendon anteriorly; the infraspinatus tendon posteriorly can be followed to its insertion on the greater tuberosity. Thickening and increased signal intensity of the supraspinatus and infraspinatus tendons indicates tendinosis. There is mild to moderate fatty atrophy of the infraspinatus along its myotendinous junction. The supraspinatus muscle appears relatively normal. Although the teres minor tendon can be followed to its insertion on the greater tuberosity, there is moderate fatty atrophy of the teres minor muscle. There is thickening and increased signal intensity of the subscapularis tendon distally indicating moderate tendinosis and perhaps undersurface fraying. The subscapularis muscle appears normal.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. A small amount of fluid is present within the subacromial/subdeltoid bursa, with strands of intermediate signal intensity in the bursa likely reflecting synovitis.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is within normal limits. There is a small amount of fluid in the glenohumeral joint. Tiny osteophytes suggest minimal osteoarthritis. Intermediate signal intensity within the superior labrum likely reflects degeneration and degenerative tearing.BICEPS TENDON: There is mild increased signal intensity within the tendon of the long head of the biceps reflecting mild tendinosis.

Full-thickness rotator cuff tear involving the supraspinatus and infraspinatus, and other findings as described above.
