目的：探讨颈部转移淋巴结分布与其原发肿瘤的相关性，以及其CT、MR影像表现特点，旨在提高病变诊断的准确率。方法搜集经手术或穿刺病理证实的126例原发肿瘤颈部转移淋巴结患者C T和（或）M RI资料，分析颈部转移淋巴结分布与其原发肿瘤的相关性，以及其影像学表现。结果多数头颈部原发肿瘤均可转移到Ⅱb区，Ⅱa区及Ⅲ区也是常见的转移部位。颈部转移淋巴结分布与其原发肿瘤的来源有较大的相关性。结论颈部转移淋巴结分布与其原发肿瘤的淋巴引流区域相关，颈部淋巴结RT OG分区对判断颈部淋巴结转移的原发肿瘤来源具有重要的价值。%Objective To explore the relationship between distribution of cervical lymph node metastasis and location of the primary tumor ,and the CT and MR features of cervical metastatic node .Methods CT and MR appearances of 126 pa-tients with cervical metastatic lymph nodes of the neoplasms proved by surgery and pathology were reviewed retrospective-ly .The relationship between distribution of cervical lymph node metastasis and location of the primary tumor was ana-lyzed .Results The lymph nodes in level Ⅱb were the most commonly involved ,followed by level Ⅱa and Ⅲ .There was an obvious relationship between distribution of cervical lymph node metastasis and location of the primary tumor .Conclu-sion Distribution of cervical lymph node metastasis is related to lymphatic drainage pathways of the primary tumor .Dis-tribution of cervical lymph node metastasis based on radiation therapy oncology group guidelines plays a valuable role in e-valuating the origin of primary tumor .
