本文报道不同部位和病理类型的肺转移性肿瘤 X 线表现的异同点及某些特点。血道转移可根据转移肿瘤的数量和大小,分为孤立性、多发性、弥漫性和粟粒性四种类型,其中多发性肺转移是各种恶性肿瘤肺转移最常见的表现,弥漫性和粟粒性肺转移较多见于血供丰富的肿瘤。通过547例的分析,就肺转移肿瘤与性别、年龄的关系,诊断与鉴别诊断,淋巴道转移的形成过程等作了简要讨论。
This article reports the similarities and differences of X-ray findings of lung metastatic tumors of different sites and pathological types and some characteristics. Hematogenous metastasis can be divided into four types: isolated, multiple, diffuse and miliary, depending on the number and size of metastatic tumors. Multiple lung metastases are the most common manifestations of lung metastases in various malignancies, diffuse and miliary. Lung metastases are more common in tumors rich in blood supply. Through the analysis of 547 cases, a brief discussion was made on the relationship between lung metastasis and sex, age, diagnosis and differential diagnosis, and the formation process of lymphatic metastasis.
