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。
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 CF 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 angiograrn 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.
