Evidence of fracture associated with bone marrow edematous changes at the acromion base associated with fluid signal and soft tissue edematous changes around the fracture site.
Subchondral cystic changes at greater tuberosity, the insertion site of supraspinatus and infraspinatus tendons.
Thickening of coracoacromial ligament causing to supraspinatus tendon impingement.
Subacromial / subdeltoid bursae detention.
Degenerative changes along with the AC joint.
Acromion type II.
