Calcium Pyrophosphate Dihydrate Crystal Deposition Disease of the Sternoclavicular Joint

Deposition of calcium pyrophosphate dihydrate (CPPD) crystals in the articular structures affects predominantly temporomandibular, knee, hip, spine, and wrist joints, and is a rare condition, often mimicking malignancy. Sternoclavicular joint is extremely rarely involved. We present a patient with swelling of the right upper extremity, in whom on computed tomography a mass posterior to the ster...

Calcium pyrophosphate dihydrate crystal deposition disease of the temporomandibular joint.

A case of a 74-year-old woman with calcium pyrophosphate dihydrate crystal deposition disease of the temporomandibular joint (TMJ) is presented. This disease rarely involves the TMJ and is not usually considered in the differential diagnosis of TMJ disorders. To our knowledge, only 23 cases have been reported in the literature and only four without any destructive changes of the condyle as in t...

Factors affecting the solubility of calcium pyrophosphate dihydrate crystals.

The solubility of triclinic calcium pyrophosphate dihydrate (CPPD) crystals was measured under varying conditions using 45Ca-labeled crystals, expressing solubility as micromoles per liter of 45Ca in solution. In a 0.1-M Tris-HC1 buffer pH 7.4, the solubility of accurately sized CPPD crystals (37-20mum) was 60muM with maximal solubility being attained after about 8 h incubation at 37degreeC. Re...
