73-year-old female with shoulder pain. Evaluation is limited by patient motion artifact.ROTATOR CUFF: There is marked thinning of the distal supraspinatus tendon just proximal to its humeral insertion, indicating chronic attritional tearing along the articular surface and likely the bursal surface of the tendon as well, with delamination of the articular surface fibers and proximal retraction. The tendon on coronal image 11 of series 11 appears to be no more than 1 mm in thickness. More posteriorly, at the interface of the supraspinatus and infraspinatus tendons, the expected location of the tendon insertion is replaced with increased signal intensity which may indicate a full-thickness component of the tear. There is mild increased signal intensity within the remainder of the tendon likely representing a combination of degeneration and tearing. There is mild atrophy of the supraspinatus muscle. There may be mild fraying of the bursal surface fibers as well as a small interstitial tear along the myotendinous junction of the infraspinatus, but we see no full-thickness tear. There is mild fatty infiltration of the infraspinatus along the myotendinous junction. There is severe fatty infiltration of the teres minor muscle, although the tendon can be traced to its insertion on the greater tuberosity. The subscapularis muscle and tendon appear intact.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid within the subacromial bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. There is no joint effusion. Evaluation of the labrum is limited due to patient motion artifact and lack of fluid within the joint. The anterior inferior labrum is enlarged with increased signal intensity likely reflecting degeneration. There is branching signal abnormality within the posterior labrum likely representing degenerative tearing.BICEPS TENDON: There is focal increased signal within the tendon of the long head of the biceps, centrally, which may reflect mild degeneration. ADDITIONAL
1. Near full-thickness to full-thickness tearing of the supraspinatus tendon as described above with relatively mild partial thickness tearing of the infraspinatus tendon.2. Severe fatty infiltration of the teres minor with intact appearing tendon.3. Acromioclavicular joint osteoarthritis and small amount of fluid within the subacromial bursa.4. Degenerative tearing of the glenoid labrum.5. Other findings as described above.
