【摘要】目的 探讨彩色多普勒超声对鼻咽癌颈部淋巴结转移的诊断价值及诊断标准。方法 对经临床和病理确诊的鼻咽癌病人65例进行颈部分区扫查，观察颈部淋巴结的大小、数目、形态、部位、内部回声，有无淋巴门结构，包膜是否完整，是否融合，液化或钙化，观察淋巴结的血流特征。结果 65例病人颈部淋巴结肿大，单侧颈部淋巴结转移42例，双侧颈部淋巴结转移23例。多为类圆形、椭圆形或不规则形，淋巴门结构消失，部分为囊实性混合回声或中央见液化坏死及钙化，且转移淋巴结以上颈部II区居多。结论 鼻咽癌颈部淋巴结转移的声像图在形态、边界、内部回声结构、血流分布特征等方面都有其特征性表现。彩色多普勒超声可为鼻咽癌颈部淋巴结转移的诊断提供重要信息。

    Efficacy of Color Doppler Sonography in the Diagnosis of M alignant

    Cervical Lymph Nodes for Nasopharyngeal Carcinoma

    【Abstract】Purpose:The aim of the study was to summarize the sonographic features of metastatic cervical lymph nodes for nasopharyngeal carcinoma (NPC) and evaluate their diagnostic values. Methods: 65 consecutive patients with clinical and biopsy proven nasopharyngeal carcinoma were underwent sonography. We analyzed the sonographic features of cervical lymph nodes with respect to size, number, shape, margin, level, internal echotexture, lymph hilum, envelope, necrosis, calcifications and color flow pattern. Results: There were 65 m alignant nodes, 42 were unilateral, 23 were bilateral. Sonographic features of metastatic lymph nodes include round, oblonga shape, irregular margin, absent of lymph node hilum, and the presence of intranodal necrosis and calcification. These metastatic lymph nodes were more common in level II. Conclusion: The m alignant cervical lymph nodes of nasopharyngeal carcinoma have specific characteristics in shape, margin, internal echotexture, and vascular pattern on sonography. Color Doppler sonography can provide reliable information for the diagnosis of m alignant cervical lymph nodes for NPC. ......
