Nontuberculous mycobacterial (NTM) pulmonary infections can be quite similar to tuberculosis, both clinically and radiologically. However, the treatment protocol is not similar. is a rare cause of NTM pulmonary infection. Herein, we aimed to evaluate and compare the computed tomography (CT) scan findings of infection in lungs. For this reason, thirty-four patients ( = 34) with lung infection were retrospectively evaluated. Diagnosis was confirmed by American Thoracic Society (ATS) guidelines and CT scans were reviewed in both lung and mediastinal windows. The average age of patients was 63 ± 14.54 years and 52.9% were male. The majority of patients had cough (91.2%) and sputum production (76.5%). Clinically, 41.2% of patients had previous history of TB (14/34), 38.2% had cardiac diseases (13/34), and 35.3% had diabetes mellitus (12/34). The most common CT findings in our study were nodular lesions (100%) and bronchiectasis (85.29%). Regarding the severity, grade I bronchiectasis was the most prevalent. Other prominent findings were tree-in-bud sign (88.2%), consolidation (52.94%), and lobar fibrosis and volume loss (67.6%). There was no significant zonal distribution of findings. In conclusion, nodular lesions and bronchiectasis are the most frequent features in CT scan of pulmonary infection.
非结核分枝杆菌（NTM）肺部感染在临床和影像学上可能与肺结核非常相似。然而，治疗方案并不相同。[原文此处缺失具体病因]是NTM肺部感染的罕见病因。在此，我们旨在评估和比较[原文此处缺失具体病因]肺部感染的计算机断层扫描（CT）结果。为此，对34例[原文此处缺失具体病因]肺部感染患者进行了回顾性评估。诊断依据美国胸科学会（ATS）指南确定，并在肺窗和纵隔窗对CT扫描结果进行了复查。患者的平均年龄为63±14.54岁，男性占52.9%。大多数患者有咳嗽（91.2%）和咳痰（76.5%）。临床上，41.2%的患者有肺结核病史（14/34），38.2%有心脏病（13/34），35.3%有糖尿病（12/34）。我们研究中最常见的CT表现为结节性病变（100%）和支气管扩张（85.29%）。就严重程度而言，I级支气管扩张最为常见。其他突出表现为树芽征（88.2%）、实变（52.94%）以及肺叶纤维化和容积缩小（67.6%）。这些表现无明显的区域分布差异。总之，结节性病变和支气管扩张是[原文此处缺失具体病因]肺部感染CT扫描中最常见的特征。
