(CPDD) an acute or chronic inflammatory arthropathy caused by deposition of calcium pyrophosphate dihydrate (CPPD) crystals in the joints and characterized by chondrocalcinosis and the presence of the crystals in synovial fluid (see also chondrocalcinosis). Clinically, it may resemble numerous connective tissue diseases, including osteoarthritis, rheumatoid arthritis, and gout, or it may be asymptomatic.
