CT诊断肺结核合并肺癌的临床应用价值分析

Analysis of the Clinical Application Value of CT in the Diagnosis of Pulmonary Tuberculosis Complicated with Lung Cancer

目的观察CT诊断肺结核合并肺癌的临床应用价值分析。方法将在我院就诊,近期(2018年1月至2020年6月)收治以肺结核合并肺癌为诊断的患者总计40例设置为实验组,并选取同期我院诊断为单纯肺结核的另40例患者作为对照组。分析两组患者症状表现和CT诊断中影像学特征。结果两组均有不同比例的患者出现发热、声音嘶哑、咯血、盗汗、呼吸窘迫、淋巴结肿的症状,但差异无统计学意义(P>0.05)。而实验组患者咳嗽、胸腔积液(血性)、胸痛(刺激性)症状比例,高于对照组,差异有统计学意义(P<0.05)。实验组中以肺部团块、条索影为主,伴有分叶征、毛刺征、棘刺征较为常见。实验组分叶征、团块影、棘刺征、毛刺征、空泡征率高于对照组(P<0.05)。结论肺结核合并肺癌患者中,并未见临床表现极其明显的特异性症状与体征,而在影像学表现中,多出现肺癌的占位性特征,或者同时出现了病灶分布不均、形态多样等于肺结核相似的影像学表现。

Objective To observe the clinical application value of CT in the diagnosis of pulmonary tuberculosis complicated with lung cancer.Methods A total of 40 patients with pulmonary tuberculosis complicated with lung cancer admitted to our hospital in the near future (from January 2018 to June 2020) were set as the experimental group,and another 40 patients diagnosed as simple pulmonary tuberculosis in our hospital during the same period were selected as the control group.The imaging characteristics of symptoms and CT diagnosis in the two groups were analyzed.Results The symptoms of fever,hoarseness,hemoptysis,night sweats,respiratory distress and lymphadenopathy were found in different proportions of the two groups,but the difference was not statistically significant (P>0.05).The proportion of cough,pleural effusion (bloody) and chest pain (irritation) in the experimental group was higher than that in the control group (P<0.05).In the experimental group,pulmonary mass and streak shadow were the main signs,accompanied by lobulation,prick and prick.The rates of leaf sign,mass shadow,prick sign,burr sign and vacuole sign in the experimental group were higher than those in the control group (P<0.05).Conclusion In the patients with pulmonary tuberculosis complicated with lung cancer,there are no obvious clinical symptoms and signs,but in the imaging manifestations,the space occupying characteristics of lung cancer are often found,or at the same time,the uneven distribution of lesions and various shapes are the same as the manifestations of imaging findings,which are similar to pulmonary tuberculosis.
