【摘要】 目的:探讨非结核分支杆菌肺病的HRCT表现及其在随访中的应用价值。方法:回顾性分析经临床确诊的50例非结核分支杆菌肺病的HRCT资料,并对随访的23例患者治疗前后的HRCT资料进行对比分析。结果:3个肺叶及以上受累占94%(47/50),上叶受累占98%(49/50)。HRCT上所有病例均能检出结节病灶及树芽征,显示有斑片状影47例,空洞29例,纤维条索影29例,支气管扩张43例。病变通常以多种形态混杂存在。23例随访患者HRCT表现:10例病灶影像学变化不明显,5例好转,8例缓慢进展,其中6例由原来的斑片影、磨玻璃影及结节影演变为空洞。结论:胸部HRCT对非结核分支杆菌肺病的诊断及随访具有重要价值。更多还原

【Abstract】 Objective:To explore the high resolution CT(HRCT) appearances of pulmonary nontuberculous mycobacterial infection and the value of HRCT in the diagnosis and follow-up of the disease.Methods:The HRCT findings of 50 cases with pulmonary nontuberculous mycobacterial(NTM) infection were reviewed.Among them,HRCT data before and after treatment were compared and analyzed in 23 patients.Results:The abnormalities involved more than 3 lobes in 47 patients,and the upper lobe was involved in 49 patients.HRCT findings:tree-in-bud sign and nodule were detected in all cases,patchy shadow in 47 cases,cavitiy in 29 cases,fibrosis in 29 cases,and bronchiectasis in 43 cases.Multiple manifestations often coexisted.HRCT performances of 23 follow-up cases:changes of imaging were not obvious in 10 cases,improved in 5 cases,slowly progressed in 8 cases,cavitiy developed from original pachy,ground-glass and nodule shadows in 6 cases.Conclusion:The chest HRCT has important value for the diagnosis and follow-up of lung NTM infection.更多还原
