The right acromioclavicular joint shows hypertrophic osteoarthropathy that assumes a callus like appearance. Consequent compression of the underlying paratendinous fat planes and the related passing part of the supraspinatus tendon. The muscle bulk of supraspinatus is remarkably diminished with diffuse fatty infiltration.The distal part of the supraspinatus tendon till its insertion shows intermediate signal on T1, PD and T2 WIs with diffuse relative thickening. No definite tendon discontinuity or gap. Excess fluid in the subacromial bursa.

Typical case of impingement with the serious consequence of supraspinatus muscle atrophy evident by the tangent sign as seen on the sagittal oblique sequences.
