我们的目的是比较由鸟分枝杆菌胞内复合体 (MAC) 和脓肿分枝杆菌引起的非结核分枝杆菌肺部疾病的 CT 表现。两名胸部放射科医生回顾性分析了 51 例 MAC 患者和 36 例脓肿分枝杆菌感染患者的薄层 CT 检查结果，了解肺部病变的模式和形态。在小结节、树芽模式和支气管扩张的存在方面，MAC 和脓肿分枝杆菌感染之间没有发现显着差异。然而，在 MAC 感染中更常见的是肺叶体积减少 (P=0.001)、结节 (p=0.018)、空腔实变 (p=0.047) 和薄壁空洞 (p=0.009)。上叶空洞形式在 MAC 组（51 名患者中的 19 名，37%）比脓肿分枝杆菌组（36 名患者中的 5 名，14%）更常见（p=0.029），而结节性支气管扩张形式在脓肿分枝杆菌组中更常见（[36 名患者中的 29 名，81%] vs. MAC 中的[51 名患者中的 27 名，53%]） （P=0.012）。总之，MAC 和脓肿分枝杆菌肺部感染的常见 CT 表现有相当大的重叠；然而，肺叶体积减少、结节、气腔实变和薄壁空腔在 MAC 中比脓肿分枝杆菌感染更常见。
We aimed to compare the CT findings of nontuberculous mycobacterial pulmonary diseases caused by Mycobacterium avium-intracellulare complex (MAC) and Mycobacterium abscessus. Two chest radiologists analyzed retrospectively the thin-section CT findings of 51 patients with MAC and 36 with M. abscessus infection in terms of patterns and forms of lung lesions. No significant difference was found between MAC and M. abscessus infection in the presence of small nodules, tree-in-bud pattern, and bronchiectasis. However, lobar volume decrease (P=0.001), nodule (p=0.018), airspace consolidation (p=0.047) and thin-walled cavity (p=0.009) were more frequently observed in MAC infection. The upper lobe cavitary form was more frequent in the MAC (19 of 51 patients, 37%) group than M. abscessus (5 of 36, 14%) (p=0.029), whereas the nodular bronchiectatic form was more frequent in the M. abscessus group ([29 of 36, 81%] vs. [27 of 51, 53%] in MAC) (P=0.012). In conclusion, there is considerable overlap in common CT findings of MAC and M. abscessus pulmonary infection; however, lobar volume loss, nodule, airspace consolidation, and thin-walled cavity are more frequently seen in MAC than M. abscessus infection.
