彩色多普勒超声对浅表软组织肿物的诊断价值

Value of Color Doppler Ultrasonography in Diagnosing Superficial Soft Tissue Masses

目的探讨高频彩色多普勒超声对浅表软组织肿物的诊断价值。方法回顾性分析2008年111月70例经手术、活检病理证实的浅表软组织肿物的声像图特征,包括肿物的部位、形态大小、内部回声、边界及其与周边组织的关系、长径与厚度比值(L/T)及病变周边与内部血流分布情况。结果超声对浅表肿块病灶的显示率为100%,良性肿瘤有脂肪瘤、表皮囊肿、滑膜囊肿、神经鞘瘤,血管瘤、异物肉芽肿等,恶性肿物包括皮肤纤维肉瘤,转移性腺癌。结论彩色多普勒超声对浅表肿块的检出、定位及物理性质可做出准确的诊断,综合分析肿物的边界、形态、内部回声及血流分布等特点对肿物的良恶性诊断具有重要价值。

Objective To evaluate the value of high-frequency color Doppler ultrasonography in diagnosing the superficial soft tissue masses. Methods The clinical data of 70 patients with superficial soft tissue masses from January to November 2008 were retrospectively analyzed. Superficial soft tissue masses was diagnosed by the surgery and biopsy. The sonographic features, including the location, morphology, size, internal echo, boundary, relationship with peripheral tissues, longitude to transverse ratio （L/T）, and the vascularity, were observed. Results The results of sonographic examination showed that 100% superficial masses could be found. Benign masses included lipoma, sebaceous cysts, synovial cysts, nerve sheath tumors, haemangioma, foreign body granulomas, etc. Malignant soft tissue tumors included fibrous sarcoma and metastatic neoplasms. Conclusions Color Doppler ultrasonography can precisely diagnose the presence, localization and the physical characters of superficial soft tissue masses. It is an excellent modality to diagnose the benign or malignant masses by analyzing the boundary, configuration, internal echo and vascularity of the masses.
