MORAIS, João et al. Sinovite Vilonodular Pigmentada do Tornozelo Tratada Artroscopicamente. Rev. Port. Ortop. Traum. [online]. 2017, vol.25, n.4, pp.311-319. ISSN 1646-2122.

Pigmented Villonodular Synovitis is a rare proliferative disorder of synovial membrane, which affects young and middle-aged adults and is usually monoarticular. This condition can be locally destructive and involve muscles, tendons, bursae, bones and skin. The most common sites of presentation are the knee and hip. The incidence of Pigmented Villonodular Synovitis ankle is between 2 to 10%. The patients often present with pain, swelling and joint effusion. Plain radiographs may show defects in adjacent bone, bone cysts and a sclerotic rim. Articular effusions may appear as densities on radiographs and computed tomography because of high iron content. Magnetic resonance imaging is useful for delineating the extent of soft tissue and bone involvement. This is a case of a patient with recurrent hemarthrosis of the ankle diagnosed with localized Pigmented Villonodular Synovitis and chondral destruction treated with arthroscopic excision of the lesion and microfractures of the talus. The localized form of Pigmented Villonodular Synovitis has an excellent prognosis and a low recurrence rate when treated surgically. Arthroscopic treatment should be considered in these patients, since it is a less invasive procedure that offers the possibility of complete excision.
