Calcium pyrophosphate dihydrate crystal deposition disease: sonographic findings.
High-resolution sonography is a rapidly evolving technique that is gaining an increasing success in the assessment of crystalline arthropathies. In calcium pyrophosphate dihydrate crystal deposition disease, the sonographic features of crystal deposition include hyperchoic spots within hyaline cartilage and/or fibrocartilage and soft tissue calcifications. The aim of this pictorial essay was to present the main findings evocative of crystal deposition in patients with pyrophosphate arthropathy.
