摘　　要：目的探讨多层螺旋CT扫描在肺部多发空洞性病变中的诊断价值。方法选取我院2011年2月—2016年2月收治的43例经病理证实的肺部多发空洞性病变为研究对象,其中原发性肺癌19例,肺结核11例,肺脓肿8例,肺真菌感染5例。对以上病例的CT下的表现以及空洞内壁光滑情况、病灶的位置、空洞的厚度等特征情况进行分析。结果肺癌、肺脓肿均以右肺多见,肺结核以右肺下叶及左肺上叶常见。肺癌患者CT下空洞内壁的不光滑性高于其他各组病变,空洞壁厚度大于其他各组病变,差异有统计学意义(P<0.05)。肺癌患者CT下空洞厚度不均匀性高于其他各组病变,但差异无统计学意义(P>0.05)。结论不同类型的肺多发空洞性病变在CT表现上特有特点,其中空洞内壁光滑情况、厚度情况对于区别病变有较高的鉴别意义。Objective To evaluate the diagnostic value of multi-slice helical CT in multiple cavitary pulmonary lesions. Methods 43 cases of pathologically proved pulmonary multiple cavitary lesions in our hospital from February 2011 to February 2016 were selected, including 19 cases of primary lung cancer, 11 cases of pulmonary tuberculosis, 8 cases of pulmonary abscess, and 5 cases of pulmonary fungal infection. The characteristics of CT, the condition of the cavity wall, the location of the lesion and the thickness of the cavity were analyzed. Results Lung cancer and lung abscesses are common in the right lung, and tuberculosis is common in the lower right lobe and upper lobe of the left lung. The wall roughness of CT patients was higher than those in other groups. The thickness of cavity wall was higher than that in other groups, the difference was statistically significant（P〈0.05）. The thickness of cavity in CT patients was higher than that in other groups, but the difference was not statistically significant（P〉0.05）. Conclusion Different types of pulmonary cavitary lesions show unique features in CT, among them, the voids, the smooth wall and the thickness of the lesions are of high differential significance in distinguishing the lesions.
