青年细支气管肺泡癌CT表现与临床病理比较分析

目的探讨青年细支气管肺泡癌(BAC)的CT表现与临床病理检查的差异,提高BAC诊断率。方法回顾性分析38例BAC患者临床资料,根据CT表现分为孤立结节组(17例)、多发结节组(11例)和肺叶实变组(10例),研究比较各型肺泡癌的影像特点与临床病理。结果孤立结节组CT表现特异型征象:分叶征、支气管充气征、胸膜凹陷征等;多发结节组CT表现为两肺弥漫多发结节状,碎路石征象,常伴有胸膜牵拉等征象;肺叶实变组CT表现为肺密度低、蜂窝肺征、血管造影征及枯树枝征等。结论熟悉BAC各型的CT表现与临床病理,利于提高本病的诊断符合率。

Comparative analysis of CT scanning and clinical pathological findings in youth with broncholoalveolar carcinoma

Objective To study the difference between CT scanning and clinical pathological findings in youth with broncholoalveolar carcinoma（BAC）.Methods The clinical data of 38 patients with BAC confirmed by pathological examination were retrospectively analyzed and they were divided into three groups,solitary nodule group（involved 17 patients）,multi-nodule group（involved 11 patients） and lobar consolidation group（involved 10 patients）,according to CT scanning.Their CT scanning and clinical pathological findings of patients in three groups were compared.Results The relative characteristic findings of CT scanning in patients with solitary nodule group were various,such as lobulation,air bronchogram and pleural indentation etc.The findings in CT scanning in patients with multi-nodule group were diffused nodules in bilateral lung fields,crazy paving pattren usually combined with pleural draw.The findings of CT scanning in patients with lobar consolidation were low lung density,beehive sign,angiogram sign,leafless tree sign and multi acinus node.Conclusion The performance of BAC images was complicated and diverse,hence thoroughly understanding the performance of various types of BAC in CT scanning and clinical pathological findings can raise the diagnostic rate of youth with BAC.
