摘　　要：目的探讨周围型小细胞未分化肺癌（SCLC）的CT表现及诊断途径。方法对22例经病理证实的周围型SCLC的临床资料及CT图像进行回顾性分析。结果22例周围型SCLC均表现为稍不规则形肿块，其中20例肿块密度均匀，15例边缘呈浅分叶，18例瘤肺交界面未见明显毛刺。全部病例未见有典型的胸膜凹陷征。17例首次检查时即在同侧的肺门及纵隔内有淋巴结增大征象。22例病理取材途径中肺穿刺活检占17例。结论CT扫描及CT导向下经皮穿刺肺活检是诊断周围型SCLC的主要途径。Objective To evaluate the CT features and diagnostic methods of peripheral small cell anaplastic carcinoma of the lung. Methods The clinical data and CT images of twenty-two patients with pathologically proven peripheral small cell anaplastic carcinoma of the lung were retrospectively analyzed. Results The lesions in all cases appeared as irregular masses, the density of masses was homogeneous attenuation in 20 and 15 cases demonstrated shallow lobulation. Spicule sign was invisible in 18 cases. No evidence of pleural indentation was seen in all cases. Hilar and mediastinal lymphadenopathy ipsilateral to tumor were found in 17 cases on initial evaluation. 17 of 22 cases were pathologically proved by biopsy. Conclusion CT scan and percutaneous puncture under CT-guided are the main diagnostic methods of peripheral small cell anaplastic carcinoma of the lung.
