肺癌空洞的CT诊断及鉴别诊断

CT diagnosis and differential diagnosis of lung cancer cavity

目的探讨肺癌空洞的CT特征。方法回顾性分析了21例经手术病理证实的肺癌空洞的CT表现,男15例,女6例,平均年龄49岁。全部病例均进行了胸部CT平扫,其中11例同时有CT增强扫描。结果21例均为单发空洞,空洞以类圆形为主,平均直径为31mm,外形以浅分叶为主,占67%(14/21);21例都是厚壁空洞,81%(17/21)的空洞内外壁均不光整,增强后空洞壁强化明显。43%(9/21)空洞周围见卫星灶。结论肺癌空洞的CT表现具有一定的特征性,根据此特征可以与肺内的其他空洞性病变鉴别。

Objective To explore the CT characteristics of primary lung cancer cavity. Methods CT findings of primary lung cancer cavities in 21 cases, proven by operation or pathology, were analyzed retrospectively. 15 males and 6 females, with an average age of 49 - years were enrolled in the study. Non - contrast enhanced CT scan was done in all patients, while additional contrast enhanced scan was performed in 11 patients out of 21. Results Solitary pulmonary cavity was found in all 21 cases. The cavity was commonly oval, averagely sized 31mm in diameter. Most of the cavities （67%, 14/21 ）were slightly lobulated. The cavity has thick wall in all cases and the wall was irregular in 81% （17/21） cases, which was significantly enhanced. The cavities are. Peri -cavity satellite nodules were revealed in 43% （9/21） cases. Conclusion There are some characteristic CT findings of lung cancer cavities, helpful in differentiating from other pulmonary cavities.
