TīmeklisPVNS is a benign proliferative disorder of synovium. It affects joints, bursae and tendon sheath, and may be diffuse or localized. X-ray may be normal. However, in very advanced cases, the synovial proliferation can be seen as uncalcified radiodense mass. Also, bone erosion due to pressure and subchondral cysts are observed.
