目的:探讨弥漫性泛细支气管炎的多排CT表现。方法:回顾性分析5例弥漫性泛细支气管炎患者CT表现与病理改变。结果:5例均见广泛分布的小叶中心性结节,无融合;2例见“树芽征”;3例细支气管壁增厚、呈柱状或环形扩张;3例可见小叶中心性肺气肿;5例均可见鼻窦炎。结论:弥漫性泛细支气管炎其影像学表现具有特征性,影像学检查尤以HRCT检查对该病早期诊断有重要临床意义。 Objective: To investigate the multi-line CT findings of diffuse panbronchiolitis. Methods: CT findings and pathological changes of 5 patients with diffuse panbronchiolitis were retrospectively analyzed. Results: In 5 cases, central lobules with central lobules were widely distributed, and there was no fusion. In 2 cases, “tree buds” were seen. In 3 cases, bronchial wall thickening was observed with columnar or annular expansion. Emphysema; 5 cases were visible sinusitis. Conclusions: The manifestations of diffuse panbronchiolitis are characteristic. The imaging examination, especially HRCT, has an important clinical significance in the early diagnosis of the disease.
