Patterns of radiographic abnormalities associated with basic calcium phosphate and calcium pyrophosphate dihydrate crystal deposition in the knee.

چکیده
Radiographs and synovial fluids from 66 knees representing 59 patients with symptomatic osteoarthritis were evaluated to determine the pattern of radiographic abnormalities associated with basic calcium phosphate (BCP), calcium pyrophosphate dihydrate (CPPD), or both crystals together. Crystals were found in 71% of fluids. In general, CPPD crystals correlated with patient age, while BCP crystals correlated with joint degeneration. Synovial fluid BCP and CPPD crystals were found together more often than either alone. Joint compartment narrowing and osteophytes in three compartments are often associated with BCP crystals.

Calcium pyrophosphate dihydrate (CPPD) is one of several types of crystal that may be deposited in the body. The term chondrocalcinosis is used to describe the radiographic appearance of calcified deposits, notably in the articular cartilage and menisci of the knees but also in other joints.' Not all calcified deposits within joints are due to calcium pyrophosphate; however, occasional depositi...

A 49 year old man is described with a polyarticular arthritis. Synovial fluid aspirated from the knee joint showed monosodium urate monohydrate and calcium pyrophosphate dihydrate by polarised light microscopy. Additionally, diphosphonate binding and scanning electron microscopy with energy dispersive analysis showed that basic calcium phosphate crystals were also present. This appears to be th...

Calcium pyrophosphate dihydrate crystal deposition disease has various clinical features, and pseudogout is one of the six clinical forms. Chondrocalcinosis is the term used to describe the radiographic appearance of the disease. A review of the literature revealed that the appearance of this type of arthropathy in the foot is infrequent. We offer a review of the disease and report an atypical ...

OBJECTIVES To investigate the hypothesis that synovial fluid (SF) from patients with osteoarthritis (OA) may contain calcium phosphate crystals that are either too small, or too few in number to be identified by conventional light microscopy techniques. METHODS Twelve SF from 11 patients with established knee OA, five SF from patients with rheumatoid arthritis (RA), and two control samples of...
متن کاملTophaceous calcium pyrophosphate dihydrate deposition disease of the knee mimicking an aggressive soft tissue tumour.
Calcium pyrophosphate crystal deposition disease (CPPD), previously pseudogout, is the second most common crystal arthropathy after gout. There is increased radiographic prevalence associated with age, trauma and several metabolic disorders. Tophaceous CPPD (T-CPPD) is a rare form of CPPD which, though non-neoplastic, mimics a bone or soft tissue malignancy. T-CPPD usually presents as a mass in...
