Pseudogout - Chondrocalcinosis

Low urgency
--

Condition in which calcium pyrophosphate crystals are deposited in the cartilage of the joints.

The cause is generally unknown, although it is thought to be of genetic origin and there are diseases that can trigger it.

In most cases there are no symptoms; if there are symptoms, they are characterised by acute episodes of joint inflammation with a warm area, redness and increased joint volume.

It is diagnosed by taking a detailed clinical history, examining the joint and taking a joint fluid sample that shows calcium pyrophosphate crystals.

Treatment is based on non-steroidal anti-inflammatory drugs, corticosteroids and/or colchicine and removal of the crystals by aspiration of the joint fluid. In severe cases, surgery may be required.
