Pseudogout is an inflammation of joints, caused by the deposition of calcium pyrophosphate (CPP) crystals in articular and periarticular tissues. Although the name is still widely used, pseudogout is now referred to as calcium pyrophosphate deposition (CPPD) disease. The name pseudogout originated from an early description of this disease in patients with an acute gout-like arthritis but who did not have gout.
