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。
Objective To explore the differences of CT features and clinicopathological examinations in young patients with bronchioloalveolar carcinoma (BAC) and to improve the diagnosis rate of BAC. Methods The clinical data of 38 patients with BAC were retrospectively analyzed. According to the CT findings, there were isolated nodule group (17 cases), multiple nodule group (11 cases) and lobar consolidation group (10 cases). Image characteristics and clinical pathology. Results The isolated nodule CT showed specific signs: lobulated sign, bronchial air inflation sign, pleural depression sign, etc.; multiple nodular CT showed diffuse multiple nodules in both lungs, signs of broken stones, often accompanied by pleural traction Other signs; lung consolidation group CT showed low lung density, cellular lung signs, angiographic sign and dry branches sign. Conclusion The familiarity with the CT manifestations and clinicopathology of various types of BAC is helpful to improve the diagnostic compliance rate of this disease.
