56-year-old female with pain in the right shoulder, evaluate for rotator cuff pathology. ROTATOR CUFF: There is increased signal intensity of the supraspinatus tendon indicating moderate tendinosis. There is also more focal high signal intensity within the distal supraspinatus tendon anteriorly at its insertion on the greater tuberosity that may represent a concealed tear, with cyst formation in the underlying humerus. The supraspinatus muscle appears normal. The tendinosis extends posteriorly to involve the infraspinatus tendon as well, but we see no frank infraspinatus tendon tear. The infraspinatus muscle appears normal. The teres minor and subscapularis tendons and muscles appear normal.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid within the subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral humeral joint alignment is within normal limits. There is trace fluid within the glenohumeral joint, but no large effusion. The glenoid labrum appears normal for age.BICEPS TENDON: The tendon of the long head of the biceps appears normal.
1. Rotator cuff tendinosis with focal insertional tearing of the anterior distal fibers of the supraspinatus that may represent a concealed tear.2. Acromioclavicular joint osteoarthritis and a small amount of fluid in the subdeltoid bursa could be associated with impingement.
