| 摘 要： | 目的:探讨细支气管肺泡癌的CT表现。方法:回顾性分析经病理证实的BAC48例,进一步了解其CT表现特征。结果:BAC按影像表现分为三种类型:孤立结节型、肺炎型、弥漫型。本组分别有30例、12例、6例。孤立结节型病灶多位于外周(96·7%),同时具有分叶、毛刺、空泡征、胸膜凹陷的22例(73·3%);肺炎型中,均匀实变的7例(58·3%),蜂窝状实变2例(16·7%);磨玻璃样改变3例(25%)。支气管气相5例(71·4%),枯枝征4例(57·1%),CT血管造影征3例(42·9%);弥漫型6例均表现为双肺弥漫性分布的腺泡结节影。HRCT有助于病灶的显示。结论:熟悉BAC的CT征象,可以提高诊断正确率,减少误诊。

| Abstract: | Objective:To study the CT findings of Bronchioloalveolar Carcinoma.Methods:Fourty-eight patients with Bronchioloalveolar Carcinoma proved pathologically were retrospectively analyzed.Results:BAC were divided into three types:solitary nodule(n=30),pneumonic-type(n=12),diffuse-type(n=6).Solitary nodule demonstrated peripheral(96.7%),22 cases had CT features of lobulated and speculated and bubble-like and pleural tag (73.3%);Homogeneous consolidation were observed in 7 cases,honeycomb consolidation in 2 cases,ground-glass shadow in 3 cases,air-bronchogram sign in 5 cases,withered tree sign in 4 cases,CT angiogram sign in 3 cases;The CT findings of diffuse-typ(n=6)were diffuse nodules in lung fields.HRCT is important in showing BAC.Conclusion:To increase the diagnostic accuracy of BAC,it is essential to be familiar with its CT features. |
