Pseudogout or calcium pyrophosphate deposition disease (CPDD) is a form of inflammatory arthritis caused by crystals forming in the joints. Swelling and pain is similar to gout, but differs in the type of crystals formed, location of inflammation (such as the knees, wrist and elbows) and most importantly, treatment options.
The cause of pseudogout is primarily unknown although genetics, aging and certain medical conditions are associated with this crystalline disease. Diagnosis involves examining the joint fluid and x-rays of the afflicted area. Treatment varies with the severity of the condition, but begins with pain relief and medications to improve joint function.
