title: [Roentgenographic features in pigmented villonodular synovitis (concerning a carpal location) (author's transl)].
abstract: Pigmented villonodular synovitis is a benign proliferation of the synovial membrane. Its pathogenesis is not well known. It results in an articular swelling without great pain. Its roentgenographic aspect is a combination of an opacity of soft tissue and epiphyseal damages, i.e. cortical erosions and lacunae surrounded by osteosclerosis. Hyperplasty of the synovial membrane is explicited by arthrography and arteriography. The authors report one case of pigmented villonodular synovitis in the carpus: that is an uncommon location of that disease which most often involves the knee.
