摘　　要：目的　分析肺部Wegener肉芽肿在HRCT上的形态学特征。 方法　对 11例病理证实的肺部Wegener肉芽肿病变进行高分辨CT扫描 ,分析病变的分布 ,形态 ,内部结构 ,肺血管、胸膜及支气管有无改变。结果　 7例 ( 63 .6% )为多病灶 ,可见短毛刺及小空洞 ,其中 6例 ( 85 .7% )出现“晕”征 ,3例支气管壁增厚及支扩 ;3例为单发病灶 ;共计 5例 ( 45 .4% )单发或并发胸膜下楔形实变伴局部胸膜增厚或积液 ;另 1例表现支气管狭窄导致肺段不张。结论　肺部Wegener肉芽肿主要表现为多发的胸膜下结节、肿块及楔形实变 ,一个病例中多种表现可以并存。Objective To analyze the HRCT features of Wegener's granulomatosis. Methods Eleven cases of lung Wegener's granulomatosis proved pathologically undertook HRCT examination. The morphologic features, distribution and the changes of the lung vessels, pleural, and the bronchus were evaluated. Results Seven cases (63.6%) have multiple lesions with short burr and small cavity. Six (85.7%) of them have ”halo” sign and 3 have bronchial ectasia. Three cases have single lesion. The total of 5 cases have wedge-shaped consolidation combined with pleural thickening and fluid. The other one manifested pulmonary atelectasis due to narrowing of bronchus. Conclusion The main manifestations of pulmonary Wegener's granulomatosis are multiple subpleural nodules, mass or wedge-shaped consolidation, all these can be found in one case.
