| ［摘要］ 目的 提高对淋巴结结核CT表现的认识。方法 搜集经病理证实的颈部淋巴结结核25例，其中男8例，女17例，全部病例均行CT增强扫描。结果 25例均为多个淋巴结同时受累，以中下颈及颈后三角区受累最常见，Ⅳ区+锁骨上区占84%，Ⅴ区占60%，CT增强表现分为4型：1型均匀强化；2型薄环状强化；3型花环状强化；4型不均匀强化。各种强化类型可同时存在，两种或两种以上强化类型同时存在占84%，以环状分隔样强化及融合多环状强化最具特征。结论 颈部淋巴结结核的CT表现有一定特征性，CT检查对本病的诊断具有重要的价值。 |

| Abstract: |
| ［Abstract］ Objective To improve the understanding of CT manifestations of cervical lymph node tuberculosis.Methods The clinical data of 25 patients of lymph node tuberculosis confimed by pathologically, including 8 men and 17 women, underwent enhanced CT scan,were retrospectively analyzed.Results Multiple lymph nodes were involved in 84% of all patients, the inferier internal jugular and supraclavicular lymph nodes were involved, in 60% of all patients,the posterior triangle lymph node were involved.The enhanced patterns on CT scan were divided into four type. Type 1:homogeneous enhancement;Type 2: Thin rim enhancement; Type 3: Corolla-like enhancement; Type 4: Heterogeneous enhancement.Various combinations of these types occurred in these patients.Two or more features mixed together were seen in 84% of all patients; a separate ring-like enhancement and/or integration of multi-ring-like enhancement were the most characteristic features.Conclusion Cervical lymph node tuberculosis has certain CT characteristics, and the CT scan has the important value for diagnosing this disease. |
