23例肺转移瘤的影像学诊断

Imaging diagnosis of pulmonary meta stasis:analysis of 23cases

目的提高对肺部转移性肿瘤的影像学诊断水平。方法回顾性分析23例经临床病理证实为肺转移瘤的影像学特征。结果将影像学表现分为五型:(1)单发结节型3例;(2)多发结节型15例;(3)粟粒结节型3例;(4)淋巴结肿大型4例(5)胸膜转移型6例。结论传统X线与胸部CT检查均为诊断肺转移瘤的主要方法,特别是后者对0.5cm以下病灶的检出率以及发现肺门、纵隔淋巴结肿大和胸膜转移效果更好。

Objective To improve the level of imaging diagn osis of pulmonary metastasis.Methods A retrospective analysis was made on imaging appearances of 23cases wi th pathologically proven pulmonary metastasis.Results The pulmonary metastasis can be divided into five types:(1)solitary node in 3cases.(2)multiple nodes in 15cases,(3)military nodes in 3cases,(4)lymphadenovarix in 4cases,and(5)pleural metastasis in 6cases.Conclusion Both the traditional X -ray and chest CT are the main methods to diagnose pu lmonary metasta-sis while the latter may be better than the former,especially the node whi ch is less than 0.5cm in the diameter a ccompanying with enlarged hilar and mediastinum can be detecte d.[
