A form of arthritis that results from the deposition of calcium pyrophosphate crystals in a joint.
The underlying cause is unknown; in rare cases, it is a complication of diabetes mellitus, hyperparathyroidism, and haemochromatosis.
Symptoms are similar to gout.
Diagnosis is from a sample of joint fluid.
Treatment is with nonsteroidal anti-inflammatory drugs (NSAIDs).
n. joint pain and swelling, resembling gout, caused by crystals of calcium pyrophosphate in the synovial membrane and fluid (see synovitis). It commonly affects the knee. X-rays may show signs of *chondrocalcinosis. Treatments include NSAIDs and colchicine. Pseudogout is one manifestation of *calcium pyrophosphate deposition disease.
a condition in which calcium pyrophosphate is deposited in joints. The most common manifestation is *pseudogout, marked by acute pain, redness, and swelling resembling gout. Alternatively it may be asymptomatic in association with *chondrocalcinosis seen on X-ray, it may occur with osteoarthritis in the affected joint, or there may be chronic inflammation of the joint.... calcium pyrophosphate deposition disease
n. the appearance of calcific material in joint cartilage, most commonly an incidental finding on X-ray of the knees in elderly patients and usually causing no symptoms. Calcification of cartilage may also be seen at the shoulder and in the fibrocartilage of the wrist. It may be associated with osteoarthritis. It is also seen less commonly in several other disorders, including Wilson’s disease, pseudogout, hyperparathyroidism, hypothyroidism, and haemochromatosis.... chondrocalcinosis
