摘要
目的:对比分析薄壁囊腔类肺癌与薄壁空洞性肺结核的MSCT征象特点,提高诊断及鉴别诊断能力。方法:回顾性分析2011-2017年本院经病理或临床证实的28例薄壁囊腔类肺癌和30例薄壁空洞性肺结核的临床资料及MSCT表现,采用卡方检验或Fisher精确概率法对比分析两组病变的CT征象。结果:两组中患者的性别构成、病灶大小、含气腔隙大小的差异无统计学意义;肺癌组平均发病年龄高于结核组,差异具有统计学意义(P<0.001);结核组空洞壁的厚度大于肺癌组囊腔壁;肺结核好发于上肺;肺癌组磨玻璃征、分叶征、短毛刺征、清楚毛糙的界面、内壁不光整、分隔、壁结节及蜂窝征的出现率高于结核组,差异具有统计学意义(P<0.05);结核组的长毛刺征、内壁光整、卫星灶、形态学Ⅲ型的出现率高于肺癌组,差异具有统计学意义(P<0.05)。随访肺癌组中出现囊壁不规则增厚、壁结节增大;结核组随访可见空洞缩小。结论:薄壁囊腔类肺癌与薄壁空洞性肺结核的CT征象有一定差异,CT检查有助于两种病变的诊断和鉴别诊断。
Objective:To comparatively analyze the MSCT findings of lung cancer with thin-walled cystic airspaces and thin-walled cavitary tuberculosis,thus to improve the ability of diagnosis and differential diagnosis.Methods:The basic clinical data and MSCT findings of 28 cases with lung cancer with thin-walled cystic airspaces and 30 thin-walled cavitary tuberculosis confirmed by pathology or clinical data from 2011 to 2017 were retrospectively and comparatively analyzed.Theχ2 test or Fisher's exact probability method were used for the statistical analysis.Results:There was no statistical difference in the gender composition,the size of lesion and air space between the two groups.The mean age of lung cancer group was higher than that of cavitary tuberculosis group,there was statistical difference(P<0.001).The wall thickness of cystic airspaces of lung cancer group was less than that of cavitary tuberculosis group.Most of tuberculosis occurred in the upper lung.The ratio of ground glass opacity,lobulation,short speculation,well defined and unsmooth interface,unsmooth inner wall,septum inside the airspace,mural nodule and honeycomb sign was higher in lung cancer group than that in the cavitary tuberculosis group with statistical difference(P<0.05).The ratio of long speculation,smooth inner wall,satellite lesions,typeⅢof morphological patterns was higher in the cavitary tuberculosis group than that in lung cancer group with statistical difference(P<0.05).In follow-up study,the air space wall thickened irregularly and the mural nodule enlarged in lung cancer group,but the cavity shrunk in tuberculosis group.Conclusion:There are certain differences in the CT features between lung cancer with thin-walled cystic airspaces and thin-walled cavitary tuberculosis,CT is quite helpful in differential diagnosis of the two diseases.
