非结核分枝杆菌肺病与耐多药肺结核的胸部CT征象对照分析

目的 探讨非结核分枝杆菌(NTM)肺病与耐多药肺结核(MDR-TB)CT影像学主要特征的异同,以提高两种疾病鉴别诊断的准确性.方法 选取2019年6月-2020年6月在我院治疗的NTM肺病患者41例作为NTM组,从同期收治的MDR-TB患者中选取38例作为MDR-TB组,比较2组一般资料、CT影像学主要特征以及病变部位...

Comparation of CT imaging characteristics between non-tuberculous mycobacterium tuberculosis and multi-drug resistant tuberculosis

Objective To investigate differences of main CT imaging features between non-tuberculous mycobacterium(NTM) tuberculosis and multi-drug resistant tuberculosis(MDR-TB) for the accuracy of differential diagnosis between the two diseases. Methods The differences of general information, CT imaging features, and lesion locations of the patients were compared between the NTM group (n=41) and mDR-TB group (n=38), the patients were all adimitted to our hospital from Jun 2019 to Jun 2020 were selected. Results Age, the proportion of complicated with pulmonary basic diseases in NTM group were higher than those in MDR-TB group, and the course of disease in NTM group was shorter than that in MDR-TB group (P<0.05) ; The lesions in NTM group were more characterized by thin-wall cavity, and the detection rate in NTM group was higher than those in MDR-TB group (P<0.05); The detection rate of thick-wall cavity, pulmonary consolidation,atelectasis, collapsed lung, lung calcification, hilar mediastinal lymph node calcification, lung volume reduction, pleural thickening, the pleural effusion in NTM group were lower than those in MDR-TB group (P<0.05). The proportion of lesions involved in the ligule lobe of left lung and the middle lobe of right lung in the NTM group was higher than that in MDR-TB group (P<0.05); the proportion of cavity involved in the ligule lobe of left lung and the middle lobe of right lung in the NTM group was higher than that in MDR-TB group (P<0.05); the proportion of bronchiectasis involved in the ligule lobe of left lung and the middle lobe of right lung in NTM group was higher than that in MDR-TB group (P<0.05). There was no significant difference in the site of nodule involvement between two groups (P>0.05). Conclusion The imaging features of NTM tuberculosis and MDR-TB are similar, but there are differences, it is easier for the former to detect thin-wall cavity and for the latter to detect thick-wall cavity, atelectasis, collapsed lung, lung calcification and other characteristics, this can provide reference for the differential diagnosis of the two diseases.
