Pseudogout fluid from knee. Vial of fluid aspirated (removed) from the knee of an 80-year-old female patient with pseudogout. Pseudogout is a condition characterised by the abnormal accumulation of calcium pyrophosphate crystals in joint cartilage, which can cause inflammation, swelling and reduced articulation. It may lead to the destruction of the joint. Joints affected by pseudogout are red, swollen and extremely tender. Treatments include the use of nonsteroidal anti-inflammatory drugs. If these fail a corticosteroid drug may be injected into the affected joints. The underlying cause of pseudogout is unknown.
