非结核分枝杆菌肺病的CT征象分析

目的：探讨非结核分枝杆菌肺病的CT影像学表现。方法：回顾性分析2005年11月至2009年11月在本院确诊的30例非结核分支杆菌肺病的CT影像学资料，研究其cT影像学特点。结果：30例患者病灶跨双肺三叶及以上分布的病例占90％（27／30）；病变通常以多种形态混杂存在，以斑片状浸润影及条索影并存为多见，占53．3％（17／30）；合并支气管扩张者占93．3％（28／30），合并空洞63．3％（19／／30）及胸膜肥厚粘连43．3％（13／30）；但淋巴结肿大及胸腔积液少见。结论：非结核分枝杆菌肺病的cT以合并支气管扩张及多部位多形态混杂为其主要特征。

CT appearance of non-tuberculous mycobacterium pulmonary disease

Objective ：To study the CT appearance of non-tuberculous mycobacterium pulmonary disease （ NTM- PD）. Mcthods：CT imaging data of 30 confirmed cases of NTM-PD,registered to our hospital between November 2005 and November 2009, were collected and retrospectively analyzed to study the imaging characteristics. Results： At least 3 lobes of the both lungs were affected in 90% （27/30） of the 30 patients. The lesions showed a multiple pattern in CT appearance,but were predominantly featured by patchy infiltrates and fibrotic strands in 53.3% （17/30） of the patients. NTM-PD was complicated with bronchiectasis in 93.3% （28/30）, cavity in 63.3% （19/30） and pleural thickening/adhesion in 43.3% （13/30） of the patients, but rarely with lymph node enlargement and pleural effusion. Conclusion：The CT appearance of non-tuberculous myeobacterium pulmonary disease was shown to be featured by complicating bronchiectasis and multiple-site, multiple-pattern lesions.
