摘　　要：目的　探讨肺大细胞癌的MSCT影像学表现。方法　回顾性分析 6例经病理证实的肺大细胞癌的MSCT影像表现。平均年龄 61.5岁 ( 4 7～ 74岁 ) ,6例均为男性 ,其中 5例有长期大量吸烟史。应用GELightSpeedQx/iplus型 4层螺旋CT机行胸部薄层扫描。结果　 6例肺大细胞癌均表现为肺内周围型单发的结节或肿块影 ,平均直径约 6.4cm ( 2～ 12cm)。病灶内未见脂肪成份 ,1例有点状钙化 ,1例有厚壁空洞。病理分期中Ⅰa期 2例 ,1b期 1例 ,Ⅲa期 3例。结论　肺大细胞癌三维重建有利于征象观察 ,CT表现缺乏一定的特异性 。Objective To analyze the multi-slice CT (MSCT) feathures of lung large cell carcinoma .Methods MSCT findings of lung large cell carcinoma proven pathologically in 6 cases were analysed retrospectively .The average age of patients was 61.5(47～74) years . 6 cases were all men and 5 cases were smokers . Chest thin slice CT scan was performed with GE LightSpeed Qx/i plus four-slice helical CT . Results In all six patients,tumors were represented as single and peripheral mass or nodule . Their mean sizes were 6.4 (2～12) cm.They did not show internal fat density.1 case showed internal calcification and 1 case showed thick-wall inanition.Pathologic staging of six patients was Ⅰa in two,Ⅰb in one ,Ⅲa in three at the time of diagnosis.Conclusion Lung large cell carcinoma are very rare tumors.Its CT findings is nonspecific.Three-dimensional reconstraction is helpful in observation of CT sign.Its last diagnosis will depend on post-operative pathology.
