CALCIUM PYROPHOSPHATE DIHYDRATE (CPPD) DEPOSITION DISEASE (PSEUDOGOUT) is a topic covered in the Harrison's Manual of Medicine.
CPPD disease is characterized by acute and chronic inflammatory joint disease, usually affecting older individuals. The knee and other large joints are most commonly affected. Calcium deposits in articular cartilage (chondrocalcinosis) may be seen radiographically; these are not always associated with symptoms.
CPPD is most often idiopathic but can be associated with other conditions (Table 164-1).
Crystals are thought not to form in synovial fluid but are probably shed from articular cartilage into joint space, where they are phagocytosed by neutrophils and incite an inflammatory response.
