Presentation
New right mid humerus pain. History of rheumatoid arthritis.
Patient Data
A calcific density measuring approximately 1 cm in the anteromedial aspect of the right proximal humeral shaft (see annotated images).
Findings may represent calcific tendinitis.
A calcific density measuring approximately 1 cm in the anteromedial aspect of the right proximal humeral shaft.
A calcified focus adjacent to the anteromedial aspect of the mid humeral bone corresponding to the findings from the radiograph, likely representing a small focus of calcific tendinitis in the teres major/latissimus dorsi tendon insertion.
Normal glenohumeral and acromioclavicular alignments. Type II acromion process. Minor degenerative change in the clavicular joint. No significant degenerative changes in the glenohumeral joint.
Subchondral cysts at the insertion of supraspinatus onto the greater tuberosity, likely intraosseous ganglion cysts.
No gross abnormality within visualized soft tissues.
Visualized lung parenchyma is within normal limits.
Annotated spot images from CT.
Case Discussion
Teres major/latissimus dorsi tendon calcific tendinitis.
Calcific tendinitis is characterized by deposits of crystalline calcium phosphate in muscular tendons.
Most commonly seen in the rotator cuff muscles tendons however virtually any tendon in the body can be affected.
Calcific tendinitis can cause focal pain.
