摘要

The radiological manifestations of calcium pyrophosphate deposition (CPPD) revolve around two main axes: the asymptomatic form and CPPD disease. The latter is a consequence of an immune response to calcium phosphate crystals. Chondrocalcinosis is broadly considered the radiographic manifestation of CPPD regardless of whether it is asymptomatic or associated with inflammatory arthritis. CPPD is associated with osteoarthritis although the direction of such association is still unclear. Apart from the detection of CPP crystals in synovial fluid, imaging (mainly conventional radiography and increasingly ultrasound) plays a central role in the diagnosis of CPPD disease. Recently, CT has been added as a diagnostic tool, especially in deep anatomic locations such as crowned dens. To date, no treatment is effective in dissolving CPP crystals. For now, the focus of current treatment strategies remains inflammation control. Our aim is to review the epidemiology, pathogenesis, and clinical and imaging manifestations of asymptomatic and symptomatic CPPD. We will also discuss recent consensus definitions and classifications of CPPD disease.
