目的研究陈旧性肺结核合并肺癌患者进行CT检查对诊断的价值。方法 55例肺结核合并肺癌患者,均使用64排螺旋CT机进行扫描并诊断,分析诊断结果。结果中心性肺癌患者占41.8%(23/55),周围型肺癌患者占58.2%(32/55),43例陈旧性肺结核病变的患者CT影像呈现出纤维索条影,以及散在分布的结节影或者肿块影及结节融合;肺癌病变在影像上可以看到肿块影且其上伴随有分叶,毛刺以及胸膜凹陷征等。12例活动性结核患者的结核病灶可见大片状或者云絮状的斑片影,四周存在小点或者片状的卫星灶,肺癌病灶则体现为高密度的团块影,同时出现分叶以及毛刺或者胸膜凹陷征等一些恶性征象。结论 CT检查对肺癌的诊断具有重要的临床价值,肺结核患者需要与周围结构改变的状况以及实验室检查结果相结合来确定是否存在合并型肺癌,以降低发生误诊的几率。
Objective To study the value of CT examination in patients with old pulmonary tuberculosis complicated with lung cancer. Methods Fifty-five patients with pulmonary tuberculosis complicated with lung cancer were scanned with a 64-slice spiral CT scanner to diagnose and analyze the diagnosis results. Results There were 41.8% (23/55) patients with central lung cancer and 58.2% (32/55) patients with peripheral lung cancer. CT images of 43 patients with obsolete pulmonary tuberculosis showed fibroinography and scattered nodules Shadow or mass shadow and nodules fusion; lung cancer lesions in the image can be seen on the shadow and it accompanied by lobulation, burr and pleural indentation and so on. 12 cases of active tuberculosis tuberculosis patients showed large patchy or cloudy patchy spots around the dot or flake satellite lesions, lung lesions are manifested as high-density mass shadow, at the same time there are lobulations and Burr or pleural indentation and some other signs of malignancy. Conclusion CT examination has important clinical value in the diagnosis of lung cancer. Pulmonary tuberculosis patients need to be combined with the results of laboratory tests to determine the presence or absence of combined lung cancer in order to reduce the chance of misdiagnosis.
