SINOVITIS VILLONODULAR PIGMENTADA FOCAL: REPORTE DE UN CASO

pigmented villonodular synovitis represents a benign synovial proliferation associated to hemosiderin deposits, which originates in bone joints, bursae or tendinous sheaths. the knee articulation is the most commonly involved joint (80%of the cases), followed by the hip joint. normally, this pathology has a diffuse presentation, and a small percentage shows a localized form. pvns displays very specific imaging features, which allows a good diagnostic approach when aided by different radiological techniques, particularly magnetic resonance imaging (mri). in this report we describe an infrequent case of focal pvns localized in the hip, which was treated at "clínica alemana", santiago, chile.
