title: [X-ray computed tomography and synovial chondrometaplasia].
abstract: Scanography allows diagnosis of radiotransparent intra-articular foreign bodies and establishment of their synovial origin, sometimes even in the absence of joint opacification. It provides an overall assessment of the joint that can be improved by arthrography. Clinical and standard radiologic pictures of primary synovial chondrometaplasia (synovial osteochondromatosis) and intra-articular foreign bodies can cause confusion if the latter are modified by secondary chondrometaplasia. Scanographic analysis of islets of chondrometaplasia suggests their primary nature in the presence of plaques of calcification of a small size, of low density and diffused throughout the image while peripheral, lamellar, dense calcifications are suggestive of secondary lesions.
