The subacromial/subdeltoid bursa is distended with a T1 and STIR isointense fluid with a gravity dependent T1/STIR hypointense layer which corresponds to the area of calcification in the comparison radiographic study, indicating milk of calcium. This collection causes mild mass effect on the underlying rotator myotendinous junction. No discrete rotator cuff tear or calcification is identified, however near the supraspinatus insertion there is some architectural distortion of the tendon fibers near their insertion on the footplate. Deep to this area within the greater tuberosity there are multiple T1/T2 hyptointense foci which appear to extend out from the footplate. There is decreased bulk of the supraspinatus muscle suggesting mild atrophy.
Incidentally, a redundant fold of the middle glenohumeral ligament and subscapularis is seen in and along the anterior glenohumeral joint due to internal rotation of the humerus at the time of scanning.
