摘要： 目的：总结分析小细胞肺癌的CT表现特点、病理诊断途径及其结果，以加强对本病的病理基础与影像表现关系的认识。方法：收集经病理证实的小细胞肺癌51例，对其CT表现进行全面回顾分析，并与病理结果进行对照分析。 结果：以中央型占绝大多数；瘤组织密实，界缘清，内缘常与纵隔肿物相融合；以肺门或纵隔旁肿块伴纵隔影增宽为其主要的CT特征表现。 结论：病理检查方法的选择直接影响诊断阳性率，认识小细胞肺癌的影像特征表现有助于病理诊断。关键词： 肺癌；小细胞；CT；诊断

Abstract: Objective: To summarize and analyze the CT features , approach and result of pathologic diagnosis in small cell lung cancer (SCLC), and study the correlation of radiologic and pathologic basis. Methods：We analyzed the CT findings of 51 cases with SCLC retrospectively. All the case were confirmed by pathology. Radiologicpathologic correlative study was done, 42 of them were observed with their first chest film. Results：The majority were central type. Tumor was solid density with distinct interface and medialmargin was merged with mediastinal mass. Hilar or mediastinaside mass with accompaning widen mediastina was the major features. Conclusion：The methods of pathologic examination effect positive ratio of diagnosis. Understanding the imaging features are helpful for clinical diagnosis of SCLC. ......
