Pyrophosphate Arthritis with Local Amyloid Deposition

Acute temporomandibular arthritis in a patient with bruxism and calcium pyrophosphate deposition disease.

The temporomandibular joint has been regarded as “gout-proof’ ( I ) . Calcium pyrophosphate deposition disease (CPDD) is also unusual at this site. There has been a report of a painless destructive lesion tantamount to a calcium pyrophosphate (CaPPi) tophus involving this joint; it occurred without history of acute attacks in the area (2). Involvement of the temporomandibular joint is not menti...

Carpal instability in rheumatoid arthritis and calcium pyrophosphate deposition disease. Pathogenesis and roentgen appearance.

The roentgen appearance and pathogenesis of carpal instability are described in an evaluation of patients and cadavers with rheumatoid arthritis and calcium pyrophosphate deposition disease. Dorsiflexion (16%) and palmar flexion (8%) instability occurs in rheumatoid arthritis, particularly in patients with moderate to advanced disease. Navicular-lunate dissociation frequently accompanies dorsif...

Calcium pyrophosphate deposition disease: clinical manifestations.

Calcium pyrophosphate deposition (CPPD) disease is an arthropathy caused by calcium pyrophosphate dihydrate (CPP) crystal deposits in articular tissues, most commonly fibrocartilage and hyaline cartilage. According to EULAR, four different clinical presentations can be observed: 1) asymptomatic CPPD; 2) osteoarthritis (OA) with CPPD; 3) acute CPP crystal arthritis; 4) chronic CPP inflammatory c...
