What is pseudogout?

Pseudogout (say: “soo-doh-gowt”) is a type of arthritis. It is sometimes called calcium pyrophosphate (say: “pie-row-foss-fate”) dihydrate crystal deposition disease. This condition causes painful swelling in one or more of your joints. It can lead to joint damage if left untreated.

Pseudogout is similar to a condition called gout. However, gout typically affects the joint in the big toe. Pseudogout usually affects larger joints, such as your knees. Also, pseudogout is caused by the build up of calcium pyrophosphate dihydrate crystals in your joints, while gout is caused by a build up of uric acid.
