Calcium pyrophosphate dihydrate (CPPD) crystal deposition disease, also known as pseudogout and pyrophosphate arthropathy, is a rheumatologic disease which is thought to be secondary to abnormal accumulation of calcium pyrophosphate dihydrate crystals within joint soft tissues.[1] The knee joint is most commonly affected.[2] The disease is metabolic in origin and its treatment remains symptomatic.[3]
