【摘要】 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。更多还原

【Abstract】 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.更多还原
