摘要
目的 :探讨孤立型细支气管肺泡癌(BAC)的CT表现 ,以提高诊断准确性。材料和方法 :收集手术证实的孤立型细支气管肺泡癌共26例 ,作常规扫描、HRCT、靶扫描以及增强扫描 ,并对CT表现进行评价。结果 :全部病例均为周围型 ,其中18例距离邻近胸膜小于2cm。常见征象分叶征(15/26)、细短毛刺(21/26)、胸膜凹陷征(22/26)及空泡征或细支气管充气征(19/26)出现率很高 ,同时所有增强病例均有明显强化(18/18) ,多结节征(12/26)出现率也较高。结论 :BAC有一定的影像学特征 ,多结节征有助于其诊断。
Purpose:To evaluate CT features of solitary bronchioloalveolar carcinoma(SBAC).Materials and methods:CT features of SBAC were analyzed in 26 cases which were verified by surgery.CT scan included routine,high-resolution,target,and contrasted scan.Results:All lesions were peripheral and 18 of them were <2cm to the pleura.The signs including lobulation,spicule,pleural indentation,and air-bronchogram were common.All 18 lesions were enhanced evidently.Multi-nodules were relatively common.Conclusion:SBAC had its characteristic CT images,and the sign of multi-nodules might be helpful to diagnosis.
