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...

Musculoskeletal Ultrasound Diagnosis in Calcium Pyrophosphate Dihydrate Crystal Deposition Disease.

Calcium pyrophosphate dihydrate (CPPD) crystal deposition disease is extremely versatile. We present the case of a 52 years old patient referred for inflammatory pain of the left knee and ankle of recent onset with intense inflammatory syndrome that mimics rheumatoid arthritis. Musculoskeletal ultrasound was able to detect effusion, hyperechoic crystals within the cartilage and fibrocartilage, ...

Calcium pyrophosphate crystal deposition disease: diagnosis and treatment

Calcium pyrophosphate dihydrate crystal deposition disease (CPPD) is an inflammatory arthritis produced by the deposition of calcium pyrophosphate (CPP) crystals in the synovium and periarticular soft tissues. It is the third most common inflammatory arthritis. Diagnosis is suspected on the basis of the clinical picture and radiographic/laboratory findings. The reference standard for the diagno...
