| Abstract: | Objective To explore imaging fingdings of pigmented villonodular synovitis (PVS) so as to improve the diagnostic accuracy of PVS. Methods Imaging data of 12 patients with PVS confirmed by operation and pathology were analyzed retrospectively.12 cases were all examined with X-ray and MR imaging,5 cases examined with CT.Results In total 12 cases, swelling of soft tissue was seen in 8 cases on plain films.CT showed subcartilaginous bony erosion in 3 cases.MRI showed synovium nodular hyperplasia irregularly, deposition of paramagnetic hemosiderin-containing in all cases,and the invasion of ligament in 5 cases , menisci in 1 case and infrapatellar fat pad in 3 cases; subcartilaginous and cartilaginous erosion in 3 cases, joint effusion in 9 cases. Conclusion PVS has typical imaging characteristics,PVS can be diagnosed accurately with MRI. |
