手指软组织肿块的高频超声诊断价值

Diagnostic value on finger parenchyma tumor by ultrasonography

目的探讨高频彩色多普勒超声对手指部常见软组织肿块病变的诊断价值。方法回顾性分析22例手指部软组织肿块的临床和二维及彩色多普勒超声表现，观察肿块的位置、大小、形态、回声及彩色血流信号等，并与手术和病理资料对照。结果22例手指部软组织肿块中，腱鞘巨细胞瘤7例，腱鞘纤维瘤3例，血管球瘤5例，腱鞘囊肿7例。声像图特征有一定差异：腱鞘巨细胞瘤形态不规则，无包膜，多数瘤体内测及较丰富血流信号。腱鞘纤维瘤有完整包膜，无血流信号。血管球瘤内部呈低回声，包膜完整，血流信号丰富，Alder分级为Ⅲ级。腱鞘囊肿为囊性结构。结论各类手指软组织肿块的声像图具有各自的特征性表现，高频超声是诊断手指软组织肿块的有效影像学方法。

Objective To explore the clinical diagnostic value of high frequency ultrasound on finger parenchyma tumor. Methods Twenty-two patients with finger parenchyma tumor were analyzed retrospectively by clinical and ultrasonographic characteristics including location, size, shape, echo, and color flow signals of tumors. Those findings were compared with pathological data after surgery. Results Out of 22 parenchyma tumor patients,tendosynovial giant cell tumor were present in 7 patients, fibrous tumor in 3 patients,glomus tumor in 5 patients, and ganglia in 7 patients. Differences between ultrasonographic appearances and pathologic features were found in parenchyma tumor. The tendosynovial giant cell tumors were demonstrated plentiful color flow signals and heterogeneous echoic mass without capsules. There was not found color flow signal but an intact membrane in tendosynovial fibrous tumors. Glomus tumors were hypoechoic with an intact membrane,abundant color Doppler signals,and Ⅲ level was classified by Alder. Ganglia were expressed in cystic structure. Conclusions Characteristic features of ultrasonographic appearance were found in different kind of parenchyma tumors. High frequency ultrasound is an effective method to diagnosis finger parenchyma tumor.
