coracoclavicular bursa
The coracoclavicular bursa, also known as the supracoracoid bursa, can be found within the angle separating the trapezoid and conoid segments of the coracoclavicular ligament . It is surrounded by varying amounts of fibro-fatty tissue. Smaller bursae associated with the coracoid process or either segments of the coracoclavicular ligament may also be found adjacently .
Clinical importance
Calcific coracoclavicular bursitis is reportedly a potential cause of chronic shoulder pain . It can be demonstrated on plain films as amorphous calcifications located in the coracoclavicular region. This is to be differentiated from ligamentous calcification which appears as streaks or lines resembling the form of ligaments in the region .
