【摘要】 目的:探讨细支气管肺泡癌的高分辨CT(HRCT)征象。方法:回顾分析经病理证实的41例细支气管肺泡癌的HRCT表现,分析有助诊断的HRCT征象及病理基础。结果:孤立结节型18例,其中15例位于肺外周或胸膜下,磨玻璃密度影10例,形态不规则或斑片状影8例,空泡征和/或空气支气管征14例,胸膜凹陷征12例;弥漫型14例,其中均匀实变7例,蜂房征4例,磨玻璃密度8例,支气管气像6例,腺泡样结节6例。结论:HRCT是细支气管肺泡癌的诊断及鉴别诊断的重要手段之一。更多还原

【Abstract】 Objective:To study the appearance of bronchioloalveolar carcinoma(BAC)on high-resolution CT.Methods:HRCT scans of 41 patients with pathologically proven BAC were retrospectively analyzed.7 HRCT findings were separately recorded into 3 types(solitary nodule,multi-nodular,diffusion type)and were assessed with pathologic correlation.Result:HRCT findings of solitary nodule(n=18)are:typical peripheral or subpleural location in 15;pulmonary lesion with irregular margin forming a stellate or patchy pattern 8;vacuole sign and/or brochiologram 14;pleural retraction 12;The features of single lesion in multi-nodular(n=9)were the same as the former;Diffuse consolidative type(n=14):lobar or segmental homogenous consolidation(n=7);"withered tree" sign(n=4);"honey comb" sign(n=6);ground-glass opacity(n=8);acinar nodules(n=6).Conclusion:HRCT is an important method to determine the diagnosis and differential diagnosis of BAC.更多还原
