摘　　要：目的探讨肺炎型肺癌与大叶性肺炎的CT影像鉴别诊断。方法选取2020年1月—2023年5月于福建省漳州市医院影像科的大叶性肺炎患者28例为LP组,并选取同期的28例肺炎型肺癌患者为PLC组,均给予胸部CT检查,对2组的CT表现进行分析。结果2组混合磨玻璃结节伴有实质性成分发生率对比,差异无统计学意义(P>0.05)。PLC组混合阴影发生率为21.43%,LP组为0;PLC组肺叶段实变发生率25.00%,LP组为0;PLC组单纯磨玻璃密度影发生率7.14%,LP组为0;PLC组单纯肺段或肺叶实变发生率25.00%,LP组为3.57%,PLC组均高于LP组(P<0.05)。PLC组蜂窝征发生率为32.14%,LP组为10.71%;PLC组血管集束征发生率为42.86%,LP组为10.71%;PLC组枯枝征发生率为21.43%,LP组为0;PLC组支气管充气征发生率为53.57%,LP组为7.14%;PLC组空泡征发生率25.00%,LP组为3.57%;PLC组均高于LP组(P<0.05)。2组病灶的密度、边缘、分布情况对比,差异无统计学意义(P>0.05)。结论胸部CT的应用可以通过蜂窝征、病灶形态、枯枝征、血管集束征、空泡征以及支气管充气征对大叶性肺炎和肺炎型肺癌进行鉴别诊断,具有一定的应用价值。Objective To explore the CT imaging differential diagnosis between pneumonic lung cancer and lobar pneumonia.Methods A total of 28 patients with lobar pneumonia who were admitted to department of imaging,Zhangzhou Municipal Hospital of Fujian Province from January 2020 to May 2023 were selected as the LP group,and 28 patients with pneumonic lung cancer during the same period were selected as the PLC group.All patients underwent chest CT examination,and the CT manifestations of the two groups were analyzed.Results There was no statistically significant difference in the incidence of mixed ground glass nodules with substantial components between the two groups(P>0.05).The incidence of mixed shadows in the PLC group was 21.43%,LP group was 0;The incidence of pulmonary consolidation in the PLC group was 25.00%,LP group was 0.The incidence of density shadows on ground glass in the PLC group was 7.14%,LP group was 0.The incidence of simple consolidation of lung segments or lobes in the PLC group was 25.00%,The LP group was 3.57%.The PLC group was higher than the LP group(P<0.05).The incidence of cellular sign in the PLC group was 32.14%,the LP group was 10.71%.The incidence of vascular bundle sign in the PLC group was 42.86%,The LP group was 10.71%.The incidence of dead branches in the PLC group was 21.43%,LP group was 0.The incidence of bronchial inflation sign in the PLC group was 53.57%,The LP group was 7.14%.The incidence of vacuolar sign in the PLC group was 25.00%,The LP group was 3.57%.The PLC group was higher than the LP group(P<0.05).There was no statistically significant difference in density,margin,and distribution between the two groups of lesions(P>0.05).Conclusion The application of chest CT can differentiate between lobar pneumonia and pneumonia type lung cancer through honeycomb sign,lesion morphology,dead branch sign,vascular bundle sign,vacuole sign and bronchial inflation sign,and has certain practical value.
