Cervical rib in the differential diagnosis of supraclavicular mass

Cervical rib is a supernumerary rib arising from the seventh cervical vertebra and ends freely in the tissue of the neck or articulates with the first rib. It can be diagnosed as an asymptomatic incidental finding on a chest radiograph or presented with supraclavicular pain or complications as thoracic outlet syndrome. The differential diagnosis often poses malignant tumor masses, because of their characteristics in the physical exam. The management is often conservative reserving surgical intervention for highly symptomatic or complicated cases. We report a case of symptomatic cervical rib and its approach from Primary Care.
