目的:探讨空洞型肺转移瘤的特殊CT表现,提高其与肺部其他空洞性疾病的鉴别诊断水平。方法:报告6例经手术及病理证实的空洞型肺转移瘤病例,分析其CT表现的特点。结果:空洞型肺转移瘤CT表现出各种空洞样,其中,小环状空洞21枚,囊样空洞3枚,不规则空洞6枚,厚壁空洞3枚,薄壁空洞伴壁结节者1枚。结论:空洞型肺转移瘤的CT表现具有一定特点,即空洞的混合性以及与实性瘤的并存性。
OBJECTIVE: To investigate the special CT features of pulmonary metastatic lung tumors and to improve their differential diagnosis with other cavitation diseases in the lung. Methods: Six cases of cavernous metastatic tumors confirmed by surgery and pathology were reported and their CT features were analyzed. RESULTS: CT imaging of cavernous lung metastases showed various kinds of voids, among which 21 were small annular cavities, 3 were cystoid cavities, 6 were irregular cavities, 3 were thick-walled cavities, and thin-walled cavities were associated with nodular neurites. 1 piece. Conclusion: The CT appearances of pulmonary metastatic lung tumors have certain characteristics, namely the mixture of cavities and the coexistence with solid tumors.
