Shoulder pain, multiple prior cuff repairs Multiple suture tracks are seen within the humeral head/greater tuberosity and there are multiple foci of metallic susceptibility artifact overlying the shoulder which relate to prior surgical intervention.ROTATOR CUFF: There is heterogeneity of signal in the distal supraspinatus tendon likely reflecting a combination of tendinosis and scar tissue. We see no fluid-filled gap to suggest a full-thickness tear. Small surface defects likely represent chronic partial-thickness tears. Also, subcentimeter foci of abnormal signal intensity within the tendon demonstrate signal characteristics of bone marrow and represent small ossicles. The above-mentioned signal heterogeneity extends posteriorly to involve the anterior fibers of the infraspinatus tendon with perhaps small cysts within the distal infraspinatus tendon near a suture anchor tract. There is no full-thickness tear of infraspinatus tendon. There is moderate fatty atrophy along the myotendinous junction of the supraspinatus tendon but more proximally the muscle belly is relatively normal. There is mild fatty atrophy of the infraspinatus muscle distally as well. The teres minor tendon and muscle are intact. There is mild tendinosis of the subscapularis tendon but no discrete tear is identified. The subscapularis muscle is normal.SUPRASPINATUS OUTLET: There is widening of the acromioclavicular joint, presumably postsurgical in nature. There is no fluid within the subacromial subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is a small amount of fluid within the joint but no joint effusion. The superior labrum is attenuated with increased signal likely reflecting degenerative tearing. The inferior labrum is intact.BICEPS TENDON: The extra-articular portion of the biceps tendon is visualized within the bicipital groove; however the tendon is not well-visualized in the rotator interval and may be torn.
1. Findings of prior rotator cuff repair. There is heterogeneous signal intensity of the supraspinatus and anterior infraspinatus tendons that we suspect represents a combination of scarring, tendinosis, and perhaps focal partial-thickness tearing along the surface; however we see no fluid-filled gap to indicate full-thickness tear.2. Other findings detailed above.
