Abstract:
Objective To study high-frequency ultrasonic features of pigmented villonodular synovitis (PVNS).Methods High-frequency ultrasonic findings in 17 cases with PVNS were analyzed and a comparison between surgical and pathological results was made.Results Of 17 cases,10 cases were diffuse type,7 cases were local type.The main high-frequency ultrasonic signs were as follows: the diffused type synovial PVNS demonstrated as hypoecho,local synovial proliferation was revealed as nodulated and heterogeneous echo,hydrarthrosis of the knee joint was present in 10 cases,the involvement of meniscus occurred in 4 cases,intra-articular cartilage and cortex erosion were showed in 5 cases.Local type PVNS was mainly demonstrated as the nodulated and hypoechoic proliferation of synovium,hydrarthrosis of the joint and cartilage erosion were not found.Conclusions High-frequency ultrasound is a valuable imaging method for diagnosing PVNS in preoperative routine screening.
