摘　　要：目的:分析超声对颈部淋巴结肿大的诊断意义。方法:对1例颈部肿块患者进行彩色多普勒超声检查,在检查颈部浅表淋巴结之前,应先确定颈总动脉和颈内静脉的位置。从颈下部开始,在颈总动脉和颈内静脉之间作横切扫查,这种扫查方法可以精确地评估任何一处的淋巴结与颈总动脉和颈内静脉之间的关系。位于甲状腺下极尾部和深面的淋巴结检查常需作吞咽试验,应用这种声像图动态观察法有助于淋巴结的检出及鉴别。穿刺活检,病理结果为金标准。结果:超声表现可见多发性圆形、椭圆形结节呈蜂窝状,结节内为低回声且回声欠均匀。皮质与髓质结构不清,边界欠清晰,其内可见暗区或弱回声斑块。CDFI显示:淋巴门样血流消失,周边血流比正常增多。病理诊断为颈部淋巴结结核与超声检查相符。结论:正确掌握彩色多普勒检查方法及颈部淋巴结肿大特征,对疾病的早期发现,鉴别均有一定的价值。Objective： To determine the value of ultrasound for mass in cervical lymph node. Methods： Neck mass in 1 patient was examined with color Doppler ultrasonography. Results： Ultrasonography showed multiple round, oval nodules, honeycomb, and hypoechoic nodules within the echo due to uniform. Cortex and medulla structure was unclear. Boundary less clear, the dark areas seen in the weak echo or plaque. CDFI showed that the lymphoid gate-like blood flow disappeared, increased peripheral blood flow than normal. Pathological diagnosis of cervical lymph node tuberculosis was in line with the ultrasound results. Conclusion： Proper understanding of methods and color Doppler characteristics of cervical lymph nodes is of certain value for early finding and differential diagnosis of the disease.
