目的探讨彩色超声在颈部结核性淋巴结与转移性淋巴结患者诊断中的临床价值。方法选取2012年2月至2016年2月吉林省结核病医院收治的110例颈部淋巴结肿大患者作为研究对象,根据病理诊断结果将其分为结核性淋巴结组(50例)与转移性淋巴结组(60例)。两组患者均行彩色超声诊断仪检查,比较两组患者超声声像图表现、血流超声表现。结果相较于结核性淋巴结组,转移性淋巴结组的有回声液化区与强回声钙化灶概率更低,差异有统计学意义(P<0.05);转移淋巴结组患者无血流的发生率显著低于结核性淋巴结组,RI值水平与中央+边缘的发生率显著高于结核性淋巴结组,差异均有统计学意义(均P<0.05)。结论彩色超声对颈部结核性淋巴结与转移性淋巴结具有较高的诊断价值,通过分析血流分布、内部回声与RI值等可以有效提示患者的病变状态,为进一步制订治疗方案提供理论依据。
Objective To investigate the clinical value of color ultrasound in the diagnosis of cervical tuberculous lymph nodes and metastatic lymph nodes. Methods A total of 110 patients with cervical lymph node enlargement who were admitted to TB Hospital of Jilin Province from February 2012 to February 2016 were selected as the research object. According to the pathological findings, they were divided into tuberculous lymph node group (n = 50) and metastatic lymph node group (60 cases). Two groups of patients underwent color ultrasound diagnostic examination, compared the two groups of patients with ultrasound sonography, blood flow ultrasound. Results Compared with tuberculous lymph node group, the probability of echoy liquefaction area and hyperechoic calcification in metastatic lymph node group was lower (P <0.05), and the incidence of no blood flow in metastatic lymph node group was significantly lower In the group of tuberculous lymph node, the RI value and central + margin were significantly higher than that of tuberculous lymph node (all P <0.05). Conclusions Color ultrasound has high diagnostic value in cervical tuberculous lymph nodes and metastatic lymph nodes. The analysis of distribution of blood flow, internal echo and RI value can effectively predict the pathological changes of patients with tuberculosis and provide a theoretical basis for further treatment.
