Coracoclavicular joints with situs inversus
Presentation
Routine health checkup.
Patient Data
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.
