56-year-old male with pain ROTATOR CUFF: There is mild increased intermediate signal within the supraspinatus tendon suggesting tendinosis although we see no tear. Mild increased intermediate signal intensity distally in the infraspinatus suggesting tendinosis with cyst formation in the underlying bone at its insertion. There is increased signal intensity more proximally at the myotendinous junction that may represent a strain. No discrete tear is evident. The teres minor muscle and tendon appear normal.Although some fibers of the subscapularis tendon can be traced to the lesser tuberosity, there is thinning of the tendon likely reflecting chronic attritional tearing as well as what appears to be frank detachment of the inferior fibers of the tendon from the lesser tuberosity suggesting a full-thickness but incomplete tear. The subscapularis muscle is within normal limits.SUPRASPINATUS OUTLET: The acromioclavicular joint is within normal limits. There is a trace amount of fluid within the anterior aspect of the subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral alignment is within normal limits. Although no fluid signal intensity is seen entering the labrum, branching intermediate signal intensity is noted in the superior labrum suggestive of a tear that probably extends into the superior fibers of the anterior labrum.BICEPS TENDON: Signal intensity of the tendon of the long head of the biceps is within normal limits. Small amount of fluid within the sheath may simply represent extension of the glenohumeral joint.ADDITIONAL
1.Findings compatible with attritional tearing of the subscapularis tendon with a full-thickness defect of the tendon inferiorly.2.Mild tendinosis affects the supraspinatus and infraspinous tendons. Mild signal at the myotendinous junction of the infraspinatus may represent a strain.3.Findings suggestive of a superior labral tear as described above of questionable clinical significance.
