摘　　要：目的:探讨细支气管肺泡癌的CT表现特点。方法:收集经手术或肺穿刺活检病理证实的细支气管肺泡癌25例,男性15,女性10例,年龄从39～74岁,平均55岁。均行螺旋CT检查,其中HRCT检查7例,增强扫描15例,根据临床、CT表现进行分析。结果:孤立结节型14例,结节中心距胸膜均小于3.1cm,病灶直径为1.4～3.5cm,CT表现有边缘光滑2例,呈分叶征6例,短毛刺征5例,胸膜凹陷征11例,含气支气管征6例,空泡征12例;炎症型或实变型5例,病变呈多个肺段或肺叶的炎症样实变,见支气管气相4例,以及蜂房状含气腔3例;弥漫结节型6例,弥漫分布粟粒状与结节状致密影,大小不等,分布不均。结论:细支气管肺泡癌影像表现复杂,需结合临床及多种影像检查结果,认真细致地综合分析,才能提高本病的诊断符合率。Objective：To study the CT morpliologic features of bmnctfioloalveolar careinoma. Methods：25 patients （male 15, femal 10, age from 39 to 74 years, average 55 years） with bronchioloalveolar carcinoma proven by surgery and biopsy were enrolled in our study on spiral CT. High resolution CT 7 cases, enhancement 15 cases.Results：There were 14 cases of solitary bronchioloalveolar carcinoma, the distance of pleura to the centre of pulmonary node was smaller than 3. lcm,node diameter from 1.4cm to 3.5cm, the CT morphologic features of nodes were margin slick 2 cases, irregular margin 6 cases, short barb 5 cases, pleural retraction 11 cases, bronchogram 6 cases, vacuole 12 cases. 5 cases of consolidation bronchioloalveolar carcinoma, the main features were multisegment or lobes inflammatory consolidation, bronchogram phase 4 cases, and honeycomb 3 cases. 6 cases of diffused bronchioloalveolar carcinoma, the main features were widespread diffusion nodes, inequality of size, anisodistribute. Condusion：The imaging features of bronchioloalveolar carcinoma are complicated, more exact diagnosis can be made after intensively investigating imaging features and clinical features.
