目的 总结腱鞘巨细胞瘤的声像图特征 ,探讨高频彩色多普勒超声对腱鞘巨细胞瘤的诊断价值。方法 总结分析了 37例经手术病理证实的腱鞘巨细胞瘤的二维和彩色多普勒超声特征。结果 腱鞘巨细胞瘤声像图及血流图特征 :1.指、趾等关节或肌腱旁实性低回声肿块 ,大部分回声均匀 ,少部分可见钙化及液化 ,后方回声增强 ;2 .肿瘤无包膜回声 ,与周围组织分界清晰 ;可压迫骨质和侵及关节囊 ;3.多数瘤体内可探及丰富血流信号。结论 高频彩色多普勒超声可作为腱鞘巨细胞瘤的首选检查手段之一。
Objective To summarize the ultrasonographic features of giant cell tumor of tendon sheath and discuss the diagnostic value of high frequency color Doppler ultrasound in giant cell tumor of tendon sheath. Methods The characteristics of two-dimensional and color Doppler ultrasound in 37 cases of giant cell tumor of tendon sheath confirmed by surgery and pathology were summarized. Results Testicular giant cell tumor of the sonogram and blood flow diagram features: 1. Finger, toes and other joints or tendon next to the solid hypoechoic mass, most of the echo uniform, a small part of the visible calcification and liquefaction, the rear echo enhancement; 2. Tumor Envelope echo, with a clear demarcation of the surrounding tissue; can compress the bone and invasion and joint capsule; 3. Most tumors can explore and enrich the blood flow signal. Conclusion High-frequency color Doppler ultrasound can be used as the first choice of detection of giant cell tumor of tendon sheath.
