肺结核与肺癌并存的CT影像研究

CT images of patients with pulmonary tuberculosis complicated with lung cancer

目的探讨肺结核合并肺癌患者的CT影像特征,为临床疾病诊断提供参考依据。方法选取2015年—2018年我院收治的肺结核合并肺癌患者50例作为观察组,另选取同期于我院治疗的单纯肺结核患者50例为对照组。观察两组患者临床症状及CT影像表现并作出对比分析。结果两组患者临床症状及体征相比,差异无统计学意义(P> 0. 05);观察组患者分叶征、毛刺状结节比例高于对照组患者,差异有统计学意义(P <0. 01),观察组患者实质内空洞比例低于对照组患者,差异有统计学意义(P <0. 01),两组患者肿物及条索影发生比例相比差异无统计学意义(P> 0. 05)。结论肺结核合并肺癌患者的CT影像学特征主要在分叶征、毛刺状结节和空洞症,临床应根据这些特征并结合其他检查进行定性诊断。

Objective To investigate the CT images of patients with pulmonary tuberculosis complicated with lung cancer and provide reference for the diagnose. Methods 50 cases of pulmonary tuberculosis and lung cancer treated in our hospital in 2015 -2018 in January- were selected as observation group, and 50 cases of simple pulmonary- tuberculosis treated in our hospital for the same period were selected as control group. The clinical symptoms and CT imaging findings of the two groups were observed and compared. Results There was no significant difference in clinical symptoms and signs between the two groups （ P 〉 0. 05 ）, and the proportion of lobular sign and burr nodular nodules in the observation group was higher than that of the control group （ P 〈 0. 01 ）, and the proportion of parenchymal cavities in the observation group was lower than that of the control group （P 〈0. 01 ）. There was no significant difference between the two groups in the incidence of tumor and streak shadow （P 〉 0. 05）. Conclusion The CT imaging features of patients with pulmonary- tuberculosis and lung cancer are mainly lobular sign, burr like nodules and cavities, which should be qualitatively diagnosed according to these features combined with other tests.
