67-year-old male with left shoulder weakness. Please note that this examination was not protocoled for evaluation of the pectoralis major muscle and its tendon. If further evaluation is clinically warranted, a dedicated chest MRI utilizing the pectoralis protocol is recommended.ROTATOR CUFF: There is mild increased signal intensity within the supraspinatus tendon suggestive of tendinosis and perhaps mild undersurface tearing. There is no discrete fluid-filled tear. There is mild fatty atrophy along the myotendinous junction of the supraspinatus muscle. The muscle otherwise is within normal limits. The infraspinatus muscle and tendon appear intact. There is mild fatty atrophy of the infraspinatus muscle along its myotendinous junction. There is perhaps minimal tendinosis of the subscapularis tendon which otherwise appears normal for the patient's age. There is however mild fatty atrophy of the superior third of the subscapularis muscle. The tear is minor muscle and tendon appear intact.SUPRASPINATUS OUTLET: There is mild to moderate osteoarthritis affecting the acromioclavicular joint with small subchondral cysts and edema type signal abnormality within the distal clavicle and acromion.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is a small amount of fluid within the glenohumeral joint without evidence of effusion. There is intermediate signal intensity within the superior labrum suggestive of degeneration.BICEPS TENDON: There is a small amount of circumferential fluid within the tendon sheath of the tendon of the long head of the biceps which may represent a mild tenosynovitis or simply fluid extending from the glenohumeral joint.ADDITIONAL
Mild degenerative arthritic changes of the shoulder and other findings, as described above.
