目的:探讨肺转移瘤的X线、CT征象及其与原发肿瘤病理类型间的关系。方法:对585例肺转移瘤患者的X线、CT征象及原发灶病理学类型进行回顾性分析。结果:多发结节型299例,出现率最高(51.1%),其中乳癌、肺癌、食道癌、宫颈癌最多见;单发结节型88例,栗粒型15例,肺门纵隔型56例,淋巴管炎型23例,胸膜型36例,浸润型2例,支气管腔内型2例,后两者出现率最低。结论:肺转移瘤的X线及CT表现多样,大部分转移瘤的病理类型与X线表现之间无直接关系,X线平片辅以CT检查可对多数肺转移瘤作出正确诊断。
Objective: To investigate the X-ray and CT features of lung metastases and its relationship with the pathological types of primary tumors. Methods: 585 cases of lung metastases in patients with X-ray, CT signs and pathological types of primary lesions were retrospectively analyzed. Results: Multiple nodules occurred in 299 cases, with the highest incidence rate (51.1%). Among them, breast cancer, lung cancer, esophageal cancer and cervical cancer were the most common. Among them, 88 were single nodules, 15 were chestnut, 56 were hilar mediastinum , Lymphangitic type in 23 cases, pleural type in 36 cases, infiltrative type in 2 cases and bronchial type in 2 cases, the latter two were the lowest. Conclusions: The X-ray and CT findings of lung metastases are diverse. Most of the metastases have no direct relationship between pathological types and X-ray findings. X-ray films combined with CT can correctly diagnose the majority of lung metastases.
