A rare case of chondrocalcinosis in the left sterno-clavicular joint

Swellings of the sternoclavicular joint: review of traumatic and non-traumatic pathologies

“…In a CT-scan-based study, the relevance of calcium pyrophosphate dihydrate (CPPD) crystal deposition in the SCJ was 17% (36/209), with a significant association between SC CPPD and osteoarthritic changes. 108 Presentation can be with acute pain and swelling of joint 109 with or without systemic symptoms. 110 Alternatively, it can present with swelling, mimicking a tumour.…”

“… 110 – 112 Treatment consists of conservative measures such as non-steroidal anti-inflammatory agents and local injection of corticosteroids. 109 Long-term medical prophylaxis for gout can be undertaken. 112 …”

Pathologie de l’articulation sterno-costo-claviculaire

“…Comme dans l'atteinte des articulations périphériques plus habituellement touchées par cette maladie (genoux, poignets), la présentation clinique consiste en une arthrite aiguë de l'articulation SCC. L'imagerie, en particulier le scanner, permet de mettre en évidence le liseré calcique intra-articulaire bien classique [21]. Une autre observation a décrit une atteinte « tophacée » avec une masse calcifiée péri-articulaire en regard de l'articulation SCC dont l'analyse au microscope ordinaire a révélé des cristaux de pyrophosphate de calcium [22].…”

Pseudogout of the Sternoclavicular Joints

“…CPPD crystal deposition disease typically occurs in the elderly, and generally affects large joints, such as the knees, wrists, hips and glenohumerals. Although the incidence of this condition is low (1,2), sternoclavicular pseudogout should therefore be kept in mind as a potential cause of a fever of unknown origin.…”
