Calcific tendinitis of supraspinatus tendon

Case contributed by Dr Utkarsh Kabra

Presentation

Acute onset severe shoulder pain

Patient Data

Age: 50 years
Gender: Female

Suboptimal study due to motion artifacts and shoulder in internal rotation.

Calcification measuring approx 4.8 x 8 mm is seen along posterior fibers of supraspinatus tendon at the attachment site with associated moderate subdeltoid bursitis.

Significant supraspinatus and infraspinatus tendinosis is seen with near complete
tear of anterior, mid fibers of supraspinatus tendon near attachment site. The tear measures approx 7 mm in transverse and 8.5 mm in antero-posterior dimensions. No significant retraction of torn fibers is seen.

Subscapularis tendinosis is seen with no significant sizable tear.

Degeneration of glenoid labrum is seen.

Partial thinning and loss of glenohumeral articular cartilage is seen with marginal osteophytes. Multiple subchondral cysts are seen in posteroinferior glenoid bone with extension into adjacent soft tissue.

Acromion is type II with significant acromioclavicular joint arthropathy, marginal osteophytes, subcortical erosions, marrow edema and joint effusion, causing reduction in the subacromial space.

Case Discussion

Calcification along posterior fibers of supraspinatus tendon at the attachment site with associated moderate subdeltoid bursitis consistent with calcific tendinitis. The patient has multiple other findings as described above, including a significant cuff tear. However, calcific tendinitis is the likely cause of the acute pain.
