目的：复习１４例以头颈部肿物就医，组织学诊断为颈淋巴结结核的ＣＴ及Ｂ超表现，旨在提高对颈淋巴结结核的影像学诊断的认识。材料与方法：女性患者１３例，男性１例。ＣＴ平扫１例，直接增强扫描１３例，Ｂ超扫描８例。结果：以内颈链下组及锁骨上下区受累最常见（９２．８％），均为多个淋巴结同时受累（１００％），病变部分或全部与邻近肌肉粘连者７８．０％，ＣＴ增强扫描分３型：Ⅰ型：均匀等密度强化；Ⅱ型：薄环形周边强化，中央低密度相互融合时呈花环状；Ⅲ型：不均质强化。各种类型可同时存在。Ⅰ型２例，Ⅰ＋Ⅲ型２例，Ⅰ＋Ⅱ＋Ⅲ型７例，Ⅱ＋Ⅲ型２例。Ｂ超扫描８例病变均呈低回声，４例回声不均。结论：影像学检查能清晰地显示颈淋巴结结核病变的数目、部位、形态的特征，表现为病变数目多，常融合成团，侵犯区域多以及多种病理改变同时存存在。
Objective: To review 14 cases of head and neck tumor for medical treatment, histological diagnosis of cervical lymph node tuberculosis and B ultrasound performance, aimed at improving the understanding of imaging diagnosis of cervical lymph node tuberculosis. Materials and Methods: Thirteen female patients and one male. CT plain scan in 1 case, direct enhanced scan in 13 cases, B-scan in 8 cases. Results: The most common internal and cervical subclavian involvement (92.8%) was with multiple lymph nodes (100%). The lesions were partially or totally associated with adjacent muscular adhesions (78.0%), CT enhanced scanning Divided into 3 types: Ⅰ type: equal density enhancement; Ⅱ type: thin ring around the enhanced, the central low density fused with each other; Ⅲ: heterogeneous enhancement. Various types can exist at the same time. 2 cases of type Ⅰ, 2 cases of type Ⅰ + Ⅲ, 7 cases of type Ⅰ + Ⅱ + Ⅲ and 2 cases of type Ⅱ + Ⅲ. 8 cases of B-scan ultrasound showed hypoechoic, 4 cases of unequal echo. Conclusion: The imaging examination can clearly show the number, location and morphology of tuberculous lymph nodes. The number of lesions, the number of the lesions, the frequently infusing area, the infringing area and many kinds of pathological changes exist simultaneously.
