Coracoacromial ligament ossification


Isolated ossification of the coracoacromial ligament is a rare finding, and in this case most likely secondary to previous trauma.

Calcification of this ligament is most often due to trauma or renal failure, with the latter often demonstrating more of a tumoral calcinosis. Ossification of the ligament is almost exclusively due to trauma.

Rotator cuff pathology should be highly suspected with this pattern of ossification, with at least a partial tear of the supraspinatus tendon almost guaranteed.
