Analysis and Experience of CT Misdiagnosis of Pulmonary Tuberculosis Complicated with Lung Cancer

Objective:To investigate the causes and experience of CT misdiagnosis in patients with pulmonary tuberculosis complicated with lung cancer,in order to reduce the misdiagnosis.Methods:65 patients examined by 64 slice MSCT with pulmonary tuberculosis complicated with lung cancer were selected.The clinical symptoms and CT imaging findings of the patients were retrospectively analyzed.Results:In the 65 patients,52 patients suffering from cough(17 irritable cough)chest pain,16 suffering from hemoptysis,23 suffering from emaciation,8 hoarseness and 13 bloody pleural effusion.23 patients had lesions in the same lobe,and 42 in different lobes.In the selected cases,there were 56 cases of peripheral lung cancer and 9 cases of central lung cancer.There were 61 lesions≤3 cm in size,and 4 lesions>3 cm.There are some differences between pulmonary tuberculosis and lung cancer,such as cavity sign,,lobulation sign,speculation sign,enhancement of lesions and lymph nodes.Conclusion:The clinical manifestations and imaging data of pulmonary tuberculosis patients complicated with lung cancer were analyzed in detail to improve the understanding of co-existence of the two diseases,which can effectively avoid misdiagnosis,provide early intervention and improve the survival rate of patients.
