目的:探讨小细胞肺癌(SCLC)的CT表现、分型及诊断途径。方法:对65例SCLC的CT表现回顾性分析,18例病理对照、观察,分析SCLC的CT表现与病理关系。结果:肺内肿块、肺门与纵隔淋巴结广泛肿大,是SCLC的CT表现特点,CT诊断的可靠性大约为80%,结合经皮穿刺活检可提高到90%。结论:CT螺旋扫描结合CT导向经皮穿刺活检与纤维支气管镜肺活检是SCLC确诊的主要手段。
Objective: To investigate the CT findings, classification and diagnosis of small cell lung cancer (SCLC). Methods: The CT findings of 65 cases of SCLC were retrospectively analyzed. 18 cases of pathological control were observed and analyzed. The CT findings and pathological relations of SCLC were observed and analyzed. Results: The masses of the lung, the hilar and the mediastinal lymph nodes were extensively enlarged. They were characteristic CT features of SCLC. The reliability of CT diagnosis was about 80%. The combined percutaneous biopsy could be increased to 90%. Conclusion: CT spiral CT combined with CT-guided percutaneous biopsy and bronchofibroscopic lung biopsy is the main method for the diagnosis of SCLC.
