摘要
目的 探讨空洞型肺转移瘤的CT表现及其与原发灶病理类型的关系。资料与方法 报告空洞型肺转移瘤 40例 13 1枚 ,分析其CT表现并与原发灶病理类型进行对比。结果 全部空洞瘤灶均与肺多发实性结节共存。共有泡样空洞 41枚 ,不规则空洞 3 3枚 ,囊样空洞 2 6枚 ,小环形空洞 3 1枚。壁厚度均匀者 61枚 ,不均匀者 70枚。瘤灶直径 <15mm者 44枚 ,15～ 2 5mm者 66枚 ,2 5～ 40mm者 17枚 ,>40mm者 4枚。洞壁厚度 <4mm者 69枚 ,4～ 15mm者 44枚 ,>15mm者 18枚。空洞型瘤灶多见于腺癌 ( 2 2例 )与鳞癌 ( 13例 ) ,二者在CT表现上各有一定特征。空洞型瘤灶的发生与其在肺内的部位无关。结论 空洞型肺转移瘤的CT表现具有一定特点 。
Objective To study CT features of cavitary pulmonary metastases (CPMs), and to investigate the possible relationship between CPMs and the pathology of the primary lesions.Materials and Methods CT findings of 131 cavitary metastatic lesions in 40 patients with pathologically-proved CPMs were retrospectively analyzed. A comparison between CT signs and the pathologic types of the primary tumors was made.Results CPMs and multiple pulmonary solid nodules coexisted in all patients. CPMs presented as bubble (n=41), irregular (n=33), cystic (n=26) or small circular (n=31) cavities, with even (n=61) or uneven (n=70) thickness of the cavity wall. Of 131 lesions, the CPM diameter less than 15mm was seen in 44, between 15～25mm in 66, 25～40mm in 17 and larger than 40mm in 4. And the wall thickness of the cavity below 4mm, between 4～15mm and over 15mm was respectively seen in 69, 44 and 18 CPMs. CPMs mainly occurred in patients whose primary malignancy was squamous cell carcinoma (n=13) or adenocarcinoma (n=22). Each had its own CT characteristics. The occurrence of CPM bore no relationship to its site in the lung.Conclusion CPM carries certain CT features and its occurrence is related to the pathologic type of the primary malignancy.
