Abstract：Objective:To investigate the NTM pulmonary disease CT performance characteristics and in differential diagnosis of pulmonary tuberculosis. Method:To retrospective analysis of the CT features of 18 cases of NTM pulmonary disease patients.Result:Nodule was the most common CT appearance,all were found in 18 cases,secondly were patchy shadow in 16 cases of total,bronchiectasis in 13 cases,empty and fiber cord each in 11 cases.These lesions were in a variety of morphology of the hybrid coexist,the majority of many on both sides of the leaf scattered,12 cases of lung involvement,16 patients had two or more than two lobes of lung involvement,17 cases of patients with upper lobe involvement,upper lobe than the lower lobe involvement.Conclusion:Nodules, patchy shadow,bronchiectasis,empty,fibers of the cable core are the most common non mycobacterium pulmonary disease manifestations of CT,but only from the image and secondary pulmonary,tuberculosis identification is difficult,many properties of lesions and involved multiple lobe is characteristic of the disease, when the above performance or the clinical rule of poor efficacy of anti tuberculosis treatment,consideration should be given to the non tuberculosis mycobacterium tuberculosis may.
