Pseudogout--CPPD arthropathy, Case reports.

Abstract

Pseudogout, or calcium pyrophosphate arthropathy, is a crystalline synovitis, characterised either by acute attacks of joint pain, which usually occur in the large joints, or by a more chronic, progressive form of joint disease. The essential features of the disease are chondrocalcinosis and the presence of pyrophosphate crystals in the synovial fluid. The exact pathogenesis is unknown. Case reports of 2 patients with confiemed pseudogout, and of 1 who is suspected to be suffering from the disease, as well as a summary of the outstanding aspects of the condition, are presented.
