目的：探讨彩色多普勒超声声像图特征在颈部淋巴结结核超声诊断中的应用。方法对89例颈部肿大淋巴结的各种超声特征进行回顾性分析，分析彩色多普勒超声诊断颈部淋巴结结核的特异性。结果其中59例临床确诊为颈部淋巴结结核，30例为非结核性淋巴结，包括转移性淋巴结或淋巴结炎。59例颈部淋巴结结核中，根据声像图的表现可分为急性炎症、干酪坏死、寒性脓肿及愈合钙化等四型。形态多呈椭圆形，L/S比值与非结核性淋巴结组相比有显著差异（ P＜0.01）。结核组中，血流动力学显示频谱形态为低阻力型，结内峰值血流速度、阻力指数与非结核组相比有显著差异（ P＜0.01）。结论颈部淋巴结结核临床表现虽然不典型，但超声声像图具有一定的特异性，有助于该病与颈部转移癌等相鉴别。“,”Objective Explore ultrasonographic characteristics of color doppler ultrasound in the diagnosis of cervical lymph node tuberculosis ultrasonic applications Methods In 89 cases of various intumescent lymph node of neck sonographic features were retrospectively analyzed, the analysis of color doppler ultrasound diagnosis of cervical lymph node tuberculosis specificity. Results 59 cases of clinical diagnosis of cervical lymph node tuberculosis, 30 cases of non tuberculous lymph nodes, including metastatic lymph nodes or lymph node phlogistic. 59 cases of cervical lymph node tuberculosis, according to the performance of ultrasonography can be divided into acute inflammation, necrosis, cheese, cold sex abscess, healing calcification iv, etc. Form more oval, L/S ratio compared with non tuberculous lymph node groups had significant difference (P < 0.01). TB group, hemodynamic type display spectrum morphology of low resistance, and the peak blood flow velocity, resistance index and non-tuberculosis group compared with significant difference (P < 0.01).Conclusion Cervical lymph node tuberculosis clinical manifestations, though not typical, but ultrasonic ultrasonographic has certain specificity, contribute to the disease that differentiates with neck metastatic carcinoma, etc.
