高频超声对体表软组织肿块的诊断价值分析

Analysis of Diagnosis Value of High Frequency Ultrasound on Superficial Soft Tissue Mass

目的分析体表软组织肿块的彩色多普勒超声表现,探讨高频彩色多普勒超声对体表软组织肿块的诊断价值。方法对87例手术病理确诊的体表软组织肿块患者术前行彩色多普勒超声检查,观察不同类型体表软组织肿块的超声表现,分析高频超声对不同类型体表软组织肿块的诊断符合率,对比观察良恶性肿块的彩色多普勒血流显像(CDFI)血流分级。结果 87例体表软组织肿块患者超声诊断80例,诊断符合率为91.95%,误诊7例中3例脂肪瘤误诊为纤维瘤,2例神经鞘瘤误诊为恶性肿瘤,1例单纯淋巴结炎性肿误诊为淋巴转移,1例血管瘤被误诊为纤维瘤。体表软组织良性肿块CDFI血流分级显著低于恶性肿块,差异有统计学意义(P<0.05)。结论高频超声对体表软组织肿块的诊断符合率高,可以确定肿块的大小、边界、形态等,且有助于体表软组织良恶性肿块的鉴别诊断。

Objective To analyze the color Doppler ultrasound performance of superficial soft tissue mass and explore its diagnosis value of high frequency ultrasound. Methods 87 patients with superficial soft tissue mass who were definitely diagnosed through pathological examination were checked by color Doppler ultrasound,the sonographic findings of different types of superficial soft tissue mass observed,with analysis of the diagnosis coincidence rate of high frequency ultrasound on different types of the mass,to compare the color Doppler flow imaging（ CDFI） blood flow grade of benign and malignant tumors. Results Of the 87 cases,80 patients with superficial soft tissue mass were correctly diagnosed by ultrasound,with 91. 95% diagnosis coincidence rate. Among 7 misdiagnosed cases,3 with lipoma were misdiagnosed as fibroma,3 with schwannoma as malignant tumor,1 with simple lymph node phlogistic sex swollen as lymph node metastases,1 with hemangioma as fibroma. CDFI blood flow grade of benign superficial soft tissue mass was significantly lower than that of malignant mass,and the difference was statistically significant（ P〈0. 05）. Conclusion The diagnosis coincidence rate of high frequency ultrasound on superficial soft tissue mass is high with diagnosis of the size,boundary,shape,etc. of the mass,which helps differential diagnosis of benign and malignant superficial soft tissue mass.
