Radiologists are frequently asked to evaluate cervical lymph nodes with CT or MR imaging to determine if metastases are present, how extensive the metastases are, and if they have spread from lymph nodes to critical adjacent structures such as the carotid artery and skull base. Accurate information of this type is essential if the most appropriate treatment is to be selected. The purpose of this report is to review the diagnostic criteria that are currently used with CT and MR imaging to diagnose metastases in cervical nodes by evaluating nodal size, shape, grouping, and necrosis and extranodal tumor spread. In addition, emphasis is placed on details that should be included in the CT and MR report, such as the location of the nodes, the presence of nodal calcification, and the presence of associated diseases such as parotid cysts that may suggest a specific diagnosis like HIV infection. Because optimal treatment planning depends on the combined information gleaned from the clinical evaluation and the imaging studies, it is essential that there be a close dialogue between clinicians and radiologists.
放射科医生经常被要求通过CT或MR成像评估颈部淋巴结，以确定是否存在转移、转移的范围以及是否已从淋巴结扩散至关键的相邻结构，如颈动脉和颅底。若要选择最合适的治疗方法，此类准确信息至关重要。本报告的目的是通过评估淋巴结大小、形状、分组、坏死及结外肿瘤扩散情况，回顾目前CT和MR成像用于诊断颈部淋巴结转移的诊断标准。此外，重点关注CT和MR报告中应包含的细节，如淋巴结位置、淋巴结钙化情况以及是否存在如腮腺囊肿等可能提示特定诊断（如HIV感染）的相关疾病。由于最佳治疗方案的制定取决于从临床评估和影像学检查中收集到的综合信息，临床医生与放射科医生之间进行密切沟通至关重要。
