Patient Data

Age: 40 years
Gender: Male

Enlarged conoid tubercle of the clavicle is seen to articulate with the tubercle on the dorsomedial surface of the coracoid process: bilateral coracoclavicular joints, a normal variant.

The heart is positioned inversely with right sided aortic arch and gastric shadow, suggestive of dextrocardia with situs inversus.

Case Discussion

Coracoclavicular joint is a true synovial diarthrosis and is a genetically determined anatomical structure.

It is usually asymptomatic, however, they are prone to develop marginal osteophytic lipping, leading to shoulder pain.

Radiologists must check for this joint as a the differential diagnosis of unexplained shoulder pain.
