摘　　要：目的探讨鼻咽癌颈部淋巴结转移的CT表现。方法回顾性分析经穿刺活检、放射治疗后CT片对比证实的212例鼻咽癌颈部淋巴结转移病例的CT表现。结果212例病例中,Ⅱ区144例,Ⅲ区8例,未见单独Ⅳ、Ⅴ、Ⅵ、Ⅶ区淋巴结转移病例,Ⅱ区合并其他区淋巴结转移者60例。单侧淋巴结转移74例,双侧淋巴结转移138例。转移淋巴结呈均匀强化64例,呈不均匀强化者148例。152例转移淋巴结均为圆形,42例转移淋巴结部分有融合,18例病例可见椭圆形转移淋巴结。结论鼻咽癌颈部淋巴结转移是自上向下发展的,这与鼻咽部淋巴引流方向有关。Objective To study, the CT manifestations of cervical lymph node metastases in nasopharyngeal carcinoma. Methods CT appearances of cervical lymph node metastases in nasopharyngeal carcinoma proved by aspiration biopsy and comparison after radiotherapy in 212 patients were reviewed. Results Of these 212 cases, level Ⅱ and level Ⅲ lymph node metastases were found in 144 cases and 8 cases respectively. No case was found for single Level Ⅳ, Ⅴ, Ⅵ or Ⅶ lymph node metastases. Level Ⅱ and other level lymph node metastases were found in 60 cases. Lymph node metastases were found in unilateral and bilateral neck in 74 and 138 cases respectively. 64 cases were shown as homogeneous enhancement and 148 cases as heterogeneous enhancement in the metastatic lymph nodes after administration of contrast medium. The shape of metastatic lymph nodes was circular in 152 cases and oval in 18 cases. Partial lymph nodes were mixed together in 42 cases. Conclusion In nasopharyngeal carcinoma ,cervical lymph node metastases develops from upper to lower part, which relates to the drainage pathway of lymph nodes.
