Calcium pyrophosphate dihydrate (CPPD) deposition disease is a heterogeneous group of diseases with CPPD crystal deposition. Aging is the most common risk factor for CPPD deposition, followed by osteoarthritis and previous injury. Occasionally, CPPD depositions are associated with familial predisposition and metabolic diseases, including hemochromatosis, primary hyperparathyroidism, hypophosphatasia, and hypomagnesemia. CPPD deposition diseases associated with primary hyperparathyroidism in Koreans have rarely been reported. Thus, we report a case of a relatively young female patient with CPPD deposition disease associated with primary hyperparathyroidism, which was diagnosed through a polarized microscopic examination of the synovial fluid and a subtotal parathyroidectomy.
