Idiopathic
calcium pyrophosphate dihydrate (CPPD) crystal deposition disease in a young male patient: a case report.
Calcium pyrophosphate deposition disease (CPPD) is a condition that is characterized by the deposit of pyrophosphate crystals into tendons, ligaments, cartilage and synovium.
The keywords "treatment," "management" "guidelines" "recommendations" "colchicine" "nonsteroidal antiinflammatory drugs" "Anakinra" and "corticosteroids" were successively associated with the terms "deposition" "crystalinduced," "micro-crystalline," "deposition," "arthropathies," or "arthritis" and with the name of the different deposition disease (e.g., for "
calcium pyrophosphate deposition" the key words "chondrocalcinosis," "
calcium pyrophosphate dehydrate crystals" and "pseudogout" were also used).
However, the physicochemical characterization and in vitro evaluation of the final properties of CPCs produced from
calcium pyrophosphate powder have not been studied systematically.
Over the last decade, ultrasonography (US) has been demonstrated to be an excellent technique for detecting
calcium pyrophosphate dihydrate (CPP) crystal deposits in joints and periarticular tissues [1-8], and the aspect of these deposits in hyaline cartilage and fibrocartilage has been described (Figure 1).
There are various imaging features for common crystal-related deposition diseases including monosodium urate,
calcium pyrophosphate dihydrate as well as hydroxyapatite depositional diseases.
It illustrates the analysis of radiographic changes in a specific joint and the common arthropathies that produce these changes, then the radiographic hallmarks of each, with chapters on rheumatoid arthritis, psoriatic and reactive arthritis, ankylosing spondylitis, osteoarthritis, neuropathic osteoarthropathy, diffuse idiopathic skeletal hyperostosis, gout,
calcium pyrophosphate dihydrate crystal deposition disease, hydroxyapatite deposition disease, miscellaneous deposition diseases, collagen vascular diseases, juvenile idiopathic arthritis, hemophilia, and mass-like arthropathies.
Three showed monosodium urate (MSU) crystals while five had
calcium pyrophosphate (CPP) crystals.
Secondary OA may affect any joint, and causes include trauma,
calcium pyrophosphate disease, rheumatoid arthritis and neuropathic arthropathy.
These opaque crystal deposits are composed of
calcium pyrophosphate dehydrate, reflecting an association with pseudo-gout.
