目的探讨肢体腱鞘巨细胞瘤(TGCT)的高频超声特点.资料与方法回顾性分析经手术及病理证实的15例肢体 TGCT 的高频超声表现及临床特点.结果15例 TGCT 共23个肿块,位于手、足部12例共20个肿块,膝部及腘窝3例3个肿块,最大径0.5~7.0 cm,平均(3.8±1.6)cm.全部肿块均边界清晰,呈椭圆形或不规则形.9例超声表现为不均匀低回声内部散在斑片状高回声区,4例呈均匀低回声型,2例呈均匀或不均匀低回声内部散在不规则无回声区.11例共15个肿块内部或边缘可见彩色血流信号,以 Alder Ⅰ~Ⅱ级为主.2例肿块邻近骨皮质凹陷,1例肿块侵入关节囊.结论 TGCT 好发于手、足小关节周围或肌腱附近,声像图主要表现为实质性低回声肿块,单发或多发,血流信号丰富.肿块可包绕肌腱、压迫骨皮质、侵犯关节囊.

Purpose To investigate the high-frequency ultrasonographic features of tenosynovial giant cell tumor (TGCT) in extremities. Materials and Methods Fifteen patients with TGCT proved by surgery and pathology underwent high-frequency ultrasound. The ultrasonic manifestations and clinical features were retrospectively reviewed. Results Among 15 cases with 23 masses, 12 cases with 20 masses were revealed in the hands or feet, 3 cases with 3 masses located in knee joints or popliteal space. The diameters ranged from 0.5 cm to 7.0 cm, with mean of (3.8±1.6) cm. All the masses were well defined with oval or irregular shape. Nine cases showed heterogeneous hypoecho with patchy hyperecho areas inside the masses. Four cases showed homogeneous hypoecho, and heterogeneous or homogeneous hypoecho with irregular anechoic areas were seen in two cases. Eleven cases with fifteen masses showed blood flow within or around the masses mainly on Alder Ⅰ-Ⅱ. The adjacent cortical depressions were seen in 2 cases. The articular capsule was invaded in 1 case. Conclusion The predilection site of TGCT is small joints of hands and feet. The ultrasonographic manifestations are mainly hypoechoic solid masses,single or multiple, with abundant blood signal. Some of them can surround the tendon, constrict bones or invade articular capsule.
