Reason: R shoulder pain, eval for rotator cuff tear History: see above. ROTATOR CUFF: Mild intermediate signal intensity within the supraspinatus tendon suggests mild tendinosis, similar to prior. There is an elongated focus of fluid signal intensity measuring just under 2 cm in length along the myotendinous junction of the supraspinatus tendon, representing an intrasubstance cyst, but we see no full-thickness or discrete surface tear of the supraspinatus tendon. The supraspinatus muscle is otherwise normal.Tiny focus of high signal intensity within the distal infraspinatus tendon at its insertion, representing a concealed interstitial tear measuring 2 to 3 mm, new from prior. The infraspinatus muscle is normal.The teres minor tendon and muscle are normal. The subscapularis tendon and muscle are normal.SUPRASPINATUS OUTLET: There is perhaps minimal spurring along the the acromion, otherwise, the AC joint appears normal. There is no fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is within normal limits. The articular cartilage is within normal limits. Within the limits of this non-arthrographic study, the glenoid labrum appears intact.BICEPS TENDON: There is minimal increased signal intensity within the intra-articular tendon of the long head of the biceps, which may reflect mild tendinosis, not necessarily of any clinical significance.
1.Small cyst within the supraspinatus tendon with mild tendinosis, but no discrete surface or full-thickness tear.2.Tiny concealed insertional tear of the infraspinatus tendon, of questionable clinical significance.
