目的分析不同病理阶段颈部结 核的MRI表现特点。方法 回顾性分析26例 手术证实的颈淋巴结结核患者的临床、 MRI及病理学资料。结果 累及单侧颈部 10例(其中单发4例)，双侧16例(均为多 发)。根据病理颈部淋巴结结核MRI表现 可分为4型：Ⅰ型(n=9)为结核结节及肉芽 肿形成；Ⅱ型(n=12)为淋巴结干酪样坏 死；Ⅲ型(n=17)为淋巴结包膜坏死；Ⅳ型 (n=19)为淋巴结干酪样坏死破溃并向周围 侵犯。22例同时具有多个病理阶段表现。 结论 MRI能准确反映颈部淋巴结结核不同 病理阶段的特征，值得应用。

Objective To analyze the MRI findings of the cervical lymph node tuberculosis in different stages. Methods The clinic, MRI and pathology data of 26 cases of the cervical lymph node tuberculosis confirmed by operation were analyzed retrospectively. Results The single neck involved in 10 cases (including single node in 4 cases), bilateral cervical involved in 16 cases(all were multiple nodes).The corresponded MRI finding of the cervical lymph node tuberculosis can be classified into four types according to the pathology. TypeⅠ(n=9): tubercle nodules and granuloma; typeⅡ(n=12): lymphoglandula caseous necrosis; type Ⅲ (n=17): destruction of lymph node capsule; type Ⅳ(n=19): lymphoglandula caseous necrosis, capsule ruptured and invaded the surrounding tissue. 22 cases were complicated with multiple pathological stages. Conclusion MRI can well demonstrate the pathological features of the cervical lymph node tuberculosis in different stages,so which is worthy of application．
