鼻咽癌治疗后颈淋巴结残留或复发的彩色多普勒信号特征

Characteristics of Color Doppler Signal of residual or relapse cervical metastasis in nasopharyngeal carcinoma

目的探讨彩色多普勒检查对鼻咽癌治疗后颈淋巴结残留或复发的多普勒信号特征。方法 51枚颈转移淋巴结经术后病理确诊鼻咽癌治疗后颈淋巴结残留或复发(共计12例患者),24枚淋巴结为反应性增生良性淋巴结(共计6例患者),手术前行彩色多普勒检查。结果鼻咽癌治疗后颈淋巴结残留或复发的淋巴结发生部位在Ⅱ、Ⅳ区,短轴直径>10 mm,长短轴比例(L/S)<2,形状为圆形或近似圆形,其内部未见淋巴门结构,为回声不均的低回声结节,多数边界清楚且无血流。少数较大(>2 cm)有血流者,表现为周边型高阻信号。结论鼻咽癌治疗后颈淋巴结残留或复发的淋巴结在发生部位、形态、内部回声方面相对有特征的表现,可根据其作结果,多可作出正确的诊断。

Objective To study the characteristics of Color Doppler Signal of residual or relapse cervical lymph nodes metastasis in nasopharyngeal carcinoma.Methods 51 residual or relapse cervical metastasis in nasopharyngeal carcinoma(12 patients) and 24 reactive lymph(6 patients) were examined by color Doppler before surgery.All patients were been proved by post-surgery pathology.Results Residual or relapse cervical metastasis in nasopharyngeal carcinoma mostly were located in II,III region,diameter >1cm,L/S> ...
