Presentation
Acute, non-traumatic onset of right shoulder pain for 1 week.
Patient Data
Increased acromion-humeral space.
Amorphous calcification near the greater tuberosity of the humeral head.
A curvilinear calcification overlying the greater tuberosity of the humeral head; reaching near the surgical neck of the humerus.
Normal glenohumeral joint and acromioclavicular joint space. No irregularity of the articular surfaces/ fracture/ dislocation/ bone lesion.
Calcification ( about 14 x 12 x 6 mm) in the posterior fibers of the supraspinatus tendon. No acoustic shadowing. Intact supraspinatus tendon.
Normal infraspinatus, subscapularis, and biceps long head tendons.
No fatty infiltration/atrophy of supraspinatus/ infraspinatus muscles.
No glenohumeral joint effusion.
Moderate effusion in the subacromial-subdeltoid bursa. Dependent tiny echogenic foci (calcium) in the bursa along with peribursal hypervascularity.
Case Discussion
Findings of supraspinatus calcific tendinitis and calcific subdeltoid-subacromial bursitis due to leak of calcium from a tendon into the bursa.
