摘要
目的探讨MRI成像在色素沉着绒毛结节性滑膜炎(PVS)诊断中的价值。方法分析经手术及病理证实的12例PVS患者的MRI表现。结果 12例患者中,有8例单发,4例多发,均累计膝关节及髋关节;有10例呈弥漫型,2例为局限型;T1WI呈等或低信号,T2WI呈高低混杂信号影。结论 MRI成像能够明确显示PVS的形态及病变范围,对于诊断具有一定的价值。
Objective To explore the clinical value of using magnetic resonance imaging（MRI） to diagnose pigmented villonodular synovitis.Methods The MRI results of 12 cases of pigmented villonodular synovitis confirmed by surgery and pathology were analyzed.Results 8 cases were sporadic,4 cases multiple,10 cases diffusive and 2 cases of focal with T1WI low signals or T2WI mixed signals.Conclusion MRI can clearly show the shape and range of pigmented villonodular synovitis.
