46 year old female with history of right shoulder pain after rotator cuff repair. ROTATOR CUFF: There is a suture anchor present within the greater tuberosity extending towards the superior facet. The supraspinatus tendon can be followed to its insertion on the greater tuberosity. There is intermediate signal intensity within the undersurface of the tendon which suggests fraying, but we see no discrete fluid filled tears. There is perhaps mild undersurface fraying of the anterior fibers of the infraspinatus, but the remainder of the muscle and tendon is unremarkable. The teres minor and subscapularis muscles and tendons are within normal limits.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the AC joint. There is a small amount of fluid located immediately deep to the coracoacromial ligament of doubtful clinical significance. Trace fluid is also seen within the subdeltoid bursa posteriorly.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is mild blunting of the superior labrum which may be due to prior debridement or chronic degeneration. Glenohumeral joint alignment is within normal limits. There is no joint effusion.BICEPS TENDON: The biceps tendon is not seen within the rotator interval or bicipital groove. Best seen on image 15 of series 1001 is a 1.5 cm cylindrical structure of intermediate signal intensity with threaded margins situated longitudinally within the soft tissues anterior to the proximal humeral diaphysis. This may reflect prior biceps tenodesis, but this structure is not currently embedded within the bone and hence may be dislodged. ADDITIONAL
1. Postoperative changes of prior rotator cuff repair with mild undersurface fraying of the supraspinatus, but no discrete tear is appreciated.2. Cylindrical structure within the soft tissues anterior to the proximal humeral diaphysis may reflect prior biceps tenodesis, however this is not embedded in bone and hence may be dislodged.3. Mild osteoarthrosis affects the AC joint.4. Blunting of the superior labrum may reflect chronic degenerative tearing or surgical debridement but is of questionable clinical significance.
