摘要
目的探讨胞内分枝杆菌肺病的CT表现特征。方法回顾性分析2015年6月至2017年12月确诊的17例胞内分枝杆菌肺病的CT表现特点。结果胞内分枝杆菌肺病累及多个肺叶,累及5个肺叶12例(70.5%)。常见征象包括:支气管扩张16例(94.1%),累及右肺中叶及左肺舌叶13例(76.4%);空洞14例(82.3%),其中厚壁空洞11例(64.7%)、薄壁空洞8例(47.1%),同时存在厚壁空洞及薄壁空洞5例(29.4%);微小结节12例(70.5%),>lcm结节2例(11.8%);斑片、实变影14例(82.3%).其他征象:肺容积丧失9例(52.3%),条索纤维影6例(35.3%),肺气肿肺大泡6例(35.3%),气胸3例(17.6%),胸腔积液1例(5.8%),肺门纵隔淋巴结钙化7例(41.2%)。结论胞内分枝杆菌肺病常累及多个肺叶,表现为支气管扩张伴多发小结节、胸膜下空洞、多发斑片实变影等多种征象混杂,有一定特征性;在细菌学明确诊断前,有助于临床诊治。
Objective To investigate the CT features of mycobacteria intracellulare pulmonary disease ( MIPD ). Methods The CT features of 17 patients with MIPD were retrospectively analyzed in our hospital from June 2015 to December 2017. Results MIPD involved multiple lung lobes, of which 12 cases ( 70.5%) involved 5 lobes. The most common imaging features were as follows: bronchiectasis ( 94.1%), involvement of right middle lobe and/or left lingular lobe ( 76.4%), cavities ( 82.3%), nodules ( 82.3%), plaque and consolidation shadow ( 82.3%). Other imaging features such as lung volume loss ( 52.3%), fibrous stripes (35.3%), emphysematous bulla ( 35.3%), pneumothorax ( 17.6%), hydrothorax ( 5.8%) and the calcification of hilar and mediastinal lymph-nodes ( 41.2%) were also observed. Conclusion MIPD has typical characteristics, such as involving multiple lung lobes, presenting with mixed signs (like bronchiectasis with multiple nodules, subpleural cavity and multiple patchy consolidation and shadow ), which may be helpful for clinical diagnosis of MIPD before bacteriological result.
