CT Imaging Differential Diagnosis of Pneumonia Type Lung Cancer and Lobar Pneumonia
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.
