摘 要:目的 探讨超声对鼻咽癌颈部转移淋巴结的诊断价值和诊断标准。方法 对经临床和病理确诊为鼻咽癌颈部淋巴结转移的初诊患者 30例 (共 96个淋巴结 ) ,行颈部肿块灰阶超声、彩色多普勒超声和多普勒能量图检查。结果 本组转移淋巴结大小从 0 4~ 5 0cm ,85%以上的长径与短径之比 <2 ,内部回声主要为不均匀的低回声 ,液化者可为液实混合回声或液性无回声 ,淋巴结皮质不均匀增厚或消失 ,淋巴结门偏心或消失 ,边界多模糊不整。血流分布主要为周边型 ( 4 7 9% )和无血流型 ( 33 3% ) ,Rl值较高 ,平均为 0 72。部分可见颈静脉受压或静脉内癌栓。结论 鼻咽癌颈部转移淋巴结的超声图像在形态、边缘、内部回声结构、血流分布、血流动力学及淋巴结包膜外转移等方面均有较为特征性的表现 ,根据二维灰阶超声和彩色多普勒超声检查结果 ,多可作出正确诊断。To assess the diagnostic value and standard of ultrasound in cervical metastasis lymph node from Nasopharyneal Carcinoma(NPC).Methods 30 patients of cervical metastasis lymph nodes fome NPC,they were diagnosed by clinical doctor and pathology,were selected.The cervical masses were examined by gray scale ultrasound,Color Dopller Flow lmaging(CDFL) and Color Dopller Energy(CDE).Results The range of diameter of metastasis lymph nodes were from 0 4cm to 5 0cm in this group.The ratio of long to short diameter(L/S) were smaller than 2 above 85%.The intra-echoes were lower echoes mainly.The liquified lymph nodes could show the mixed echoes or no-echoes.The skin-texture thickened no-even or disappeared.The gates of lymph nodes were partial or disappeared.The border more were indistinct and no regular.The distribution of blood stream mainly were around types(47 9%) and no-blood types(33 3%).RI were higher,average was 0 72.Some cases showed jugular veins to be oppressed,or cancers plug in jugular veins.Conclusion The ultrasounic image of cervical metastasis lymph nodes from NPC have comparativly characteristic expression in shape,border,intra-echo structure,distribution of blood stream,hemodynamics and metastasis out of wrap membrane of lymph nodes,the most can be diagnosed correctly according to the results of gray scale ultrasound and Color Dopller imaging.
