Areas of low T1 and high T2 signal intensity are seen throughout the marow cavity of the humerus , campatible with red marrow reconversion. The acromion is type II in morphology. Mild capsular hypertrophy is seen the acromioclavicular joint , with mild degenerative changes to the distal clavicle . Focal subcortical cystic change overlies the anterior margin of the greater tuberosity/humeral head. Can you explain this in layman s terms. Thank you
