Abstract： 目的认识肺非结核性分支杆菌病的X线和CT表现.方法回顾性分析经确诊的22例肺非结核性分支杆菌病的X线胸片表现,其中10例同时有CT扫描.记录异常所见和主要累及的肺叶;比较胸片和CT所见的异同.结果胸片显示:(1)全部病例都有病变;(2)病变多数为两侧多叶分布(17例),右侧比左侧多(20∶ 16,),上叶比下叶多(18∶ 15);(3)在病变形态上斑片状实变(19例)、空洞(18例)、纤维性变(14例)、结节(12例)是胸片上的主要表现;(4)多数病例 (19例)多种病变同时出现.CT则以结节最常见(10例均可见),其次为实变和空洞,各为8例,此外尚可见5例支气管扩张、3例"树芽征"和2例纵隔淋巴结肿大,这些征象在胸片上均未能检出.结论气腔实变、空洞、结节、纤维化是胸片的常见表现,在CT上还可见支气管扩张、"树芽征"和纵隔淋巴结肿大.该病变的形态和分布难以和继发型肺结核区别,多种病变同时累及多肺叶是该病的特点.
