肺结核合并肺炎患者结节或肿块的CT表现与鉴别诊断

CT findings and differential diagnosis of nodules or masses in patients with pulmonary tuberculosis complicated with pneumonia

目的:对肺结核合并肺炎患者结节或肿块的CT表现以及鉴别诊断进行探讨。方法:研究50例肺结核合并肺炎患者,且均符合此次研究的纳入标准以及排除标准,依次实施CT平扫、CT增强扫描。就两种检查方法的临床诊断情况展开分析和数据对比。结果:对两种检查方法诊断情况进行比较,CT增强扫描组准确率更高,数据之间有显著差异,有统计学意义(P<0.05);CT增强扫描显示,在显影方面,肺结核合并肺炎与肺癌的差异性显著,有统计学意义(P<0.05);CT表现显示肿块内部存在结节状钙化,存在斑片条索影、空泡影、结节影。病灶存在分叶征、毛刺征以及棘状突起。结论:CT增强扫描对肺结核合并肺炎以及肺癌的鉴别有显著价值,临床诊断率高。

Objective To investigate the CT findings and differential diagnosis of nodules or masses in patients with pulmonary tuberculosis complicated with pneumonia.Methods 50 patients with pulmonary tuberculosis and pneumonia were studied,and all of them met the inclusion criteria and exclusion criteria of this study.CT scan and CT enhancement scan were performed in turn.Analysis and data comparison were conducted on the clinical diagnosis of the two examination methods.Results The diagnosis of the two methods was compared.The accuracy of the CT-enhanced scan group was higher,and there was a significant difference between the data(P<0.05).The CT-enhanced scan showed that the tuberculosis complicated with pneumonia in the development.The difference with lung cancer was statistically significant(P<0.05).CT findings showed nodular calcification inside the mass,and there were patches,empty bubbles and nodules.There are lobulation signs,burr signs and spinous processes in the lesions.Conclusion CT enhanced scan has significant value in the identification of tuberculosis with pneumonia and lung cancer,and the clinical diagnosis rate is high.
