摘要
①目的探讨大叶型细支气管肺泡癌的影像学诊断特征。②方法对１８例经病理证实的大叶型细支气管肺泡癌病人的Ｘ线和ＣＴ表现进行了分析比较。③结果Ｘ线表现为按叶、段分布的肺实变。ＣＴ表现包括蜂窝状改变、磨玻璃样阴影和大叶性均匀性实变。ＣＴ血管造影征７例，支气管充气征１０例，其中６例呈枯枝征。④结论大叶型细支气管肺泡癌病人胸部Ｘ线平片无特异性，而蜂窝状改变、ＣＴ血管造影征和枯枝征对其诊断具有相对特异性。
Objective To evaluate the diagnostic value of X ray and CT findings of lobar bronchoalveolar carcinoma. Methods X ray and CT findings of 18 patients with lobar bronchoalveolar carcinoma verified by pathology were analyzed. Results X ray films showed lobar pneumonic infiltrative shadow. CT images manifestations were honeycomb sign within the lesion, frosfed glass like shadow and lobar airspace consolidation. CT angiogram sign presented in 7 cases. Air bronchogram appeared in 10 cases, of which 6 cases manifested withered tree sign. Conclusion X ray fingings were not characteristic. Honeycomb sign, CT angiogram sign and withered tree sign were relatively specific and had diagnostic characteristics.
