There is increased signal within the infraspinatus tendon compatible with tendinopathy but no discrete fluid filled tear. There is intrasubstance tearing of the posterior fibers of the supraspinatus tendon. There is increased signal within the distal fibers of the supraspinatus tendon compatible with tendinopathy. There is insertional tearing of the superior fibers of the subscapularis muscle.
