80-year-old female with right shoulder pain. Suboptimal examination secondary to the patient's inability to complete the examination. Only axial and coronal oblique sequences were obtained. Suboptimal examination secondary to patient motion artifact.ROTATOR CUFF: There is perhaps a interstitial tear of the supraspinatus tendon just proximal to the level of its insertion on the greater tuberosity extending proximally to the level of the myotendinous junction. There is near full thickness tearing of the undersurface fibers of the subscapularis tendon at the level of its insertion. The supraspinatus, infraspinatus, and teres minor tendons and muscles are otherwise grossly intact although evaluation of the rotator cuff is suboptimal on this examination.SUPRASPINATUS OUTLET: Mild degenerative changes affect the acromioclavicular joint with subchondral cyst formation within the distal clavicle.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is a large glenohumeral joint effusion with foci of low signal intensity internally suggesting synovitis. Degenerative changes affect the glenohumeral joint with subchondral cyst formation within the glenoid. Otherwise no bone marrow signal abnormality is identified.BICEPS TENDON: The long head of the biceps tendon is poorly visualized but appears to be dislocated medial to the bicipital groove. There is increased signal abnormality and thickening of the extra-articular portion of the long head of the biceps tendon suggestive of chronic tendinosis and longitudinal split tearing.ADDITIONAL
1. Limited examination. Large glenohumeral joint effusion with foci of low signal intensity internally suggesting a synovitis. Septic arthritis/superimposed infection could be considered in the correct clinical setting. Nonspecific inflammatory changes of the deltoid muscle and rotator cuff musculature.2. Limited evaluation of the rotator cuff with apparent interstitial tearing of the supraspinatus tendon and near full thickness tearing of the subscapularis.3. Medial dislocation of the long head of the biceps tendon which is poorly visualized. Findings suggestive of chronic tendinosis/longitudinal split tearing of the extra-articular portion of the biceps tendon.
