Figure 3: MRI of the right shoulder joint. Coronal T1-weighted (a) and (b) (FS) after IV contrast images of the right shoulder showing dense enhancement of a markedly thickened shoulder joint synovium as well as the subacromial and the subdeltoid bursae with joint effusion is noted. A focal 1 cm area of erosion and underlying trabecular bone enhancement in the greater tuberosity of the humerus and a full thickness tear of supraspinatus tendon with enhancing edges are evident. There is also associated degeneration of the acromioclavicular joint with hypertrophy of its capsule.
