Abstract

The pigmented vellonodular sinovitis (PVNS) is benign neoplasm with synovial proliferation and hemosiderin deposit, characterized by large compromising joints, especially the knee. At present, two variants of clinics, the diffuse form (PVNSD) and the localized (PVNSL) are described. Arthroscopic synovectomy and radiosynoviorthesis (RSO) is the treatment that has shown the best functional results. Nuclear magnetic resonance is an appropriate method for conducting the diagnosis of PVNSL.

La sinovitis vellonodular pigmentada (SVP) es una neoplasia benigna con proliferación sinovial y depósito de hemosiderina, se caracteriza por comprometer grandes articulaciones, en especial la rodilla. En la actualidad se describen dos variantes clínicas, la forma difusa (SVPD) y la localizada (SVPL). La sinovectomía artroscópica y sinovectomía por radiación conforman el tratamiento que ha demostrado mejores resultados funcionales. La resonancia magnética nuclear es un método adecuado para establecer el diagnóstico de la SVPL.
