50-year-old male patient with left shoulder pain after breaking up a fight three days ago. Evaluate for cause of left shoulder pain. ROTATOR CUFF: There is increased signal intensity within the superior aspect of the subscapularis muscle along the myotendinous junction likely representing a muscle strain. Also, there is increased signal intensity within the superior tendons of the subscapularis which may represent interstitial tearing, but we see no discrete full-thickness rotator cuff injury. The muscles and tendons of the supraspinatus, infraspinatus, and teres minor are intact.SUPRASPINATUS OUTLET: There is prominence of the distal end of the clavicle. Trace fluid within the subacromial bursa is not necessarily of any current clinical significance.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral alignment is within normal limits. There is apparent detachment of the anterior/superior labrum from the underlying glenoid which may represent a normal variant foramen. We otherwise see no evidence of a labral tear given this nonarthrogram evaluation.BICEPS TENDON: The long head of the biceps tendon is intact and positioned normally within the bicipital groove. ADDITIONAL
Strain injury of the subscapularis tendon with interstitial tearing, but no full-thickness rotator cuff tear.
