The practice specializes in treating difficult cases through tertiary care and destination medicine. Using simple light microscopy, UA crystals are needle-like in shape, with different sizes. The principle mechanism underlying pseudogout is deposition of calcium pyrophosphate dihyrate (CPP). Most often, it is asymptomatic, but it may simulate gout and osteoarthritis. The crystals are rhomboid-shaped, weakly positively birefringent, and difficult to see. OHSU In arthritis: Crystalloid arthritis. The gold standard for a definitive diagnosis of CPPD disease is the identification of CPD crystals in synovial fluid. The recommended conservative treatment for pseudogout is pharmacologic management with NSAIDs, as well as the judicious use of intra-articular steroid injections [1, 19]. Pseudogout, also known as chondrocalcinosis, is a common joint disease caused by deposition of calcium pyrophosphate dihydrate (CPPD) crystals. Dr. Betty Keller answered.
