摘要
目的：探讨细支气管肺泡癌CT表现特点与组织病理的相关性。方法：收集经手术或穿刺活检病理证实的细支气管肺泡癌30例,男14例,女16例,年龄40-75岁,平均62岁。采用螺旋CT增强17例,平扫13例。CT图像上观察病灶的部位、大小、密度分布、内部结构及边缘特征,并评价其征象与组织病理的相关性。结果：单发结节型18例,实变型9例,弥漫小结节型3例。单发结节型主要征象：胸膜牵引征9例（50%）,磨玻璃征16例（88.8%）,支气管征10例（55.5%）,空泡征14例（77.7%）。实变型主要征象：枯树枝征6例（66.6%）,蜂房征4例（44.4%）,碎路石征3例（33.3%）,血管造影征2例（22.2%）,弥漫小结节型主要征象：两肺不对称、不均匀弥漫分布大小不等结节,结节融合倾向,伴有母瘤2例（66.6%）。结论：细支气管肺泡癌的影像表现复杂,对各型的征象深入细致地分析,可提高本病的诊断符合率。
Objective：To evaluate the correlation between the CT morphologic features and histopathologic findings of solitary bronchioloalveolar carcinoma（BAC）.Methods：30 patients （male, 14, femal, 16, aged from 40 to 75 years, owerage 62 years） with bronchioloalveolar carcinoma proven by surgery and biopsy were enroled in our study. The correlation between CT morphologic features and tumor growth was analyzed. Results：There were 3 types of BAC, in which 18 cases were of solitary nodule, 9 cases were of consolidation type, 3 eases were of the diffused nodular type. In the solitary nodule type, the main features were pleural traction 9 cases （85.7%）, ground glass appearance 16 cases （88.8 % ）, air bronchogram 10 cases（55.5%）, vacuoles 14 cases. In consolidation type, the main features were leafless tree sign 6 eases（66.6% ）, honeycomb sign 4 eases（44.4%） ,crazy paring pattern in 3 eases（33.3% ）, angiograra sign 2 cases（22.2%）. Conclusion：The imaging features of BAC are complicated, more exact diagnosis can be made after intensively investigating imaging features.
