摘　　要：目的观察手部局限性腱鞘巨细胞瘤(L-GCTTS)的常规超声特征。方法回顾性分析65例手部单发L-GCTTS患者,根据病灶位置将其分为手指组(n=45)及其他部位组(手背/手掌/手腕,n=20),对比2组患者临床资料,观察病灶超声表现及其差异。结果65例L-GCTTS病灶均边界清晰,多表现为形态规则的低回声病灶。手指组与其他部位组患者性别、年龄,病灶最大径、最外侧点与体表垂直距离及其Adler血流信号差异均有统计学意义(P均<0.05)。结论手部L-GCTTS常规超声多表现为肌腱周边边界清晰、形态规则伴后方回声增强的低回声病灶;典型手指与手背/手掌/手腕L-GCTTS病灶的常规超声表现存在差异。Objective To observe the conventional ultrasonic characteristics of localized giant cell tumors of tendon sheath(L-GCTTS)in hand.Methods Data of 65 patients with single L-GCTTS lesion in hand were retrospectively analyzed.The patients were divided into finger group(n=45)and other parts group(back of hand/palm/wrist,n=20)according to the location of GCTTS lesions.The clinical data of L-GCTTS patients were compared between groups,and the ultrasonic characteristics of L-GCTTS lesions in hand were comparatively observed.Results All 65 L-GCTTS lesions had clear boundaries,most presenting as regular hypoechoic lesions.There were significant differences of patients'gender,age,the maximum diameter of lesion and the vertical distance between body surface and outermost point,also of Adler blood flow signals of lesions between finger group and other parts group(all P<0.05).Conclusion Hand L-GCTTS manifested as hypoechoic lesion around tendons with clear boundary,regular shape and posterior acoustic enhancement,and typical L-GCTTS of finger and back of hand/palm/wrist were different on conventional ultrasonography.
