| 目的 探讨胞内分枝杆菌肺病的CT特征，并与堪萨斯分枝杆菌、脓肿/龟分枝杆菌肺病比较。方法 回顾性分析经临床及实验室检查证实的35例胞内分枝杆菌肺病、18例堪萨斯分枝杆菌肺病和22例脓肿/龟分枝杆菌肺病的胸部CT表现，比较其CT特征。结果 胞内分枝杆菌肺病病灶多分布于双肺（33/35，94.29%）、累及多个肺叶（18/35，51.43%）或全部肺叶（16/35，45.71%），主要表现为索条影（34/35，97.14%）、实变（33/35，94.29%）、小叶中心结节和树芽征（32/35，91.43%）、胸膜增厚（32/35，91.43%）、磨玻璃密度影（31/35，88.57%）、牵拉性支气管扩张（30/35，85.71%）、非牵拉性支气管扩张（25/35，71.43%）、结节（24/35，68.57%）、肺内钙化（24/35，68.57%）和空洞（23/35，65.71%）。胞内分枝杆菌肺病磨玻璃密度影多于堪萨斯分枝杆菌（P=0.001）、脓肿/龟分枝杆菌肺病（P<0.001）。胞内分枝杆菌肺病空洞壁厚于堪萨斯分枝杆菌（P=0.019）、脓肿/龟分枝杆菌肺病（P=0.024）。胞内分枝杆菌肺病肺内钙化多于堪萨斯分枝杆菌（P=0.014）、脓肿/龟分枝杆菌肺病（P=0.007）。结论 相比堪萨斯、脓肿/龟分枝杆菌肺病，胞内分枝杆菌肺病CT表现具有一定特征性，有助于鉴别诊断。 |

| Objective To explore CT characteristics of mycobacterium intracellulare pulmonary diseases compared with mycobacterium kansasii, mycobacterium abscess/chelonei pulmonary diseases. Methods CT images of 35 patients with mycobacterium intracellulare pulmonary diseases, 18 with mycobacterium kansasii pulmonary disease and 22 with mycobacterium abscess/chelonei pulmonary disease confirmed by clinical data and laboratory tests were retrospectively analyzed, and imaging findings were evaluated and compared. Results Mycobacterium intracellulare pulmonary disease involved both lungs (33/35, 94.29%), multiple lobes (18/35, 51.43%) or all lobes (16/35, 45.71%). CT characteristics included cord shadow (34/35, 97.14%), air space consolidation (33/35, 94.29%), centrilobular nodules or tree in bud (32/35, 91.43%), thickened pleura (32/35, 91.43%), ground glass opacity (31/35, 88.57%), traction bronchiectasis (30/35, 85.71%), non-traction bronchiectasis (25/35, 71.43%), nodes (24/35, 68.57%), calcification (24/35, 68.57%) and cavity (23/35, 65.71%). Ground glass opacity was more frequently observed in mycobacterium intracellulare than mycobacterium kansasii (P=0.001) and mycobacterium abscess/chelonei pulmonary disease (P<0.001). Walls of the cavity were thicker in mycobacterium intracellulare than mycobacterium kansasii (P=0.019) and mycobacterium abscess/chelonei pulmonary disease (P=0.024). Calcifications were more frequently observed in mycobacterium intracellulare than in mycobacterium kansasii (P=0.014) and mycobacterium abscess/chelonei pulmonary disease (P=0.007). Conclusion Compared with mycobacterium kansasii and abscess/chelonei pulmonary disease, CT findings of mycobacterium intracellulare have certain characteristics, which may be helpful to differential diagnosis. |
