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 ,最终诊断将依赖于手术后的病理结果
Objective To investigate the imaging features of large cell lung cancer (MSCT). Methods Retrospective analysis of 6 cases of pathologically confirmed large cell lung cancer by MSCT imaging. The mean age was 61.5 years (range, 47-74 years). All 6 patients were male, of whom 5 had a long history of massive smoking. Application of GELightSpeedQx / iplus 4-slice spiral CT chest thin layer scan. Results All the 6 cases of pulmonary large cell carcinoma presented as solitary pulmonary nodules or lumps with an average diameter of 6.4cm (2 ~ 12cm). There was no fat in the lesion, 1 case had calcification, 1 case had thick-walled cavity. Pathological staging of Ⅰ a in 2 cases, 1b in 1 case, Ⅲ a in 3 cases. Conclusion Three-dimensional reconstruction of pulmonary large cell carcinoma is helpful for the observation of the signs. The CT manifestations lack certain specificity. The final diagnosis will depend on the postoperative pathological findings
