浅表软组织肿块的超声检查评价

目的探讨二维高频超声及彩色多普勒超声对浅表软组织肿块的诊断价值.方法对121例浅表软组织肿块应用二维高频超声及彩色多普勒超声进行检查和分析.全部病例均经手术和病理学检查证实.结果良性肿块102例(其中脂肪瘤65例,腱鞘囊肿12例,神经鞘瘤7例,神经纤维瘤2例,血管瘤8例,结核脓肿5例,内膜移位1例).恶性肿块19例(其中恶性神经鞘瘤5例,恶性纤维组织细胞瘤4例,隆突性皮肤纤维肉瘤4例,脂肪肉瘤4例,恶性颗粒细胞瘤1例,横纹肌肉瘤1例).良性肿块中边界不清者40例(39%),圆度系数＞2.0者59例(57.8%),内部回声多半分布均匀,彩色血流检出率20.58%.恶性肿块边界清晰者10例(52.6%),圆度系数＜1.5者12例(63.1%),内部回声多半不均匀,彩色血流检出率100%.结论二维高频和彩色多普勒超声有助于确定浅表软组织肿块的形态、大小及深度,区分肿块的囊实性与血流特征,具有一定的临床应用价值.

Ultrasonographic Features of Superficial Soft Tissue Masses

Objective To evaluate the value of two-dimensional hign frequency and color Doppler ultrasonography in the diagnosis of superficial soft tissue masses Methods A total of 121 patients with superficial soft tissue masses were examined and analyzed with two-dimensional high frequency and color Doppler ultrasonography All of the patients were verified by operation and pathological examination Results A total of 102 cases were proved as benigh masses Among them,lipoma was in 65 cases,ganglions in 14 cases,hemangioms(8 cases),neurilemoma (7cases),neurinoma (2 cases),tuberculosis abscess (5 cases) and endometriosis (1 case).Ninteen cases were proved as malignant masses,among them malignant neurilemoma was (in 5 cases),malignant fibr-ohisliocytoma (5 cases),liposarcoma (4 cases),fibro sarcoma (4 cases) and malignant gradulocytoma (1 case) and rhabdomyosarcoma(1 case) The boundaries of the masses were hardly defined in 40 benign cases (39%) and the roundness index was > 2 in 59 cases of benign lesions The detective rate of color flow signals was 20 58% in benign lesions whereas the boundaries were clearly defined in 10 malignant cases The roundness index was < 1 5 in 12 cases (63 1%) The echogenicity was heterogeneous in distribution in the most of malignant lesions The color flow detective rate was 100% Conclusions Two-dimensional high frequency and color Doppler ultrasongraphy is helpful not only to determine the morphology,size and depth of the superficial soft tissue masses but also to differenciate the cystic from solid echotexutre and to demonstrate the vasculature pattern of the masses Therefore,it is valuable in the clinical application
