What Was the Differential Diagnosis of the Joint Symptoms?
A young patient presenting with a febrile syndrome associated with arthralgias and myalgias could suffer from a wide variety of inflammatory processes, including inflammation due to various viral and bacterial infections. The localization of the patient’s arthralgia in the hip and supraclavicular joints suggests that the arthralgias did not belong to simply constitutional symptomatology, but were more likely to be due to arthritis (i.e., joint inflammation). The differential diagnosis of acute and chronic arthritis is shown in Box 1.
