目的分析淋巴结反应性增生的CT表现及CT的诊断价值。方法回顾性分析13例经手术及病理证实的淋巴结反应性增生的CT表现。结果13例淋巴结反应性增生中,单独侵犯颈外侧淋巴结7例,同时侵犯颈外侧区及面淋巴结、颏下淋巴结各2例,1例侵犯腋窝及腹股沟淋巴结,1例为颈、腋、纵隔、腹膜后区和腹股沟淋巴结同时肿大。肿大淋巴结短径最小0.6 cm,最大2.6 cm,平均1.6 cm。肿大淋巴结孤立存在12例,仅1例有融合。1例因相互融合而密度不均,12例密度均匀并有明显强化,增强后CT值增加19.1~113.2 HU,平均59.1 HU。结论淋巴结反应性增生的CT表现有一定的特征性,CT检查对该病的定性诊断与鉴别诊断具有重要价值。
Objective To analyze the CT findings of lymph node reactive hyperplasia and the diagnostic value of CT. Methods A retrospective analysis of 13 cases of pathologically confirmed lymph node reactive hyperplasia of CT findings. Results In 13 cases of lymph node hyperplasia, 7 cases were infiltrated by cervical extranodal lymph nodes alone, 2 cases with lateral cervical lymph nodes and sub-lingual lymph nodes, 2 cases were infiltrated with axillary and inguinal lymph nodes, 1 case was neck, axillary, mediastinum, Retroperitoneal and inguinal lymph nodes at the same time swollen. Swollen lymph node minimum diameter of 0.6 cm, the largest 2.6 cm, an average of 1.6 cm. There are 12 cases of swollen lymph nodes isolated, only 1 case of fusion. One patient had uneven density due to mutual fusion. The density of 12 patients was even and obviously enhanced. The CT value increased by 19.1-113.2 HU with an average of 59.1 HU. Conclusion The CT findings of lymph node reactive hyperplasia have certain characteristics. CT examination is of great value in the qualitative diagnosis and differential diagnosis of the disease.
