摘　　要：目的：探讨多层螺旋CT（MSCT）在诊断肺大细胞神经内分泌癌（LCNEC）中的价值。方法：回顾性分析经病理证实的19例LCNEC患者的临床和CT资料。结果：19例LCNEC 中，6例为中央型，13例为周围型；病灶呈类圆形或不规则形，边缘可见分叶状13例、毛刺5例；病灶直径3～7cm，平均（4．60±1．99）cm；可见坏死7例，出血2例，钙化1例；胸膜凹陷征3例，阻塞性肺炎及阻塞性肺不张2例，胸腔积液4例，肺门淋巴结或纵隔淋巴结肿大9例，伴远处转移7例。结论：LCNEC的CT表现无明显特征性，最终确诊需结合临床和病理检查。Objective：To explore the diagnostic value of MSCT in large cell neuroendocrine carcinoma （LCNEC）. Methods：The clinical and CT data of 1 9 patients with LCNEC confirmed by pathology were analyzed retrospectively.Re-sults：The main CT findings of LCNEC：central type （n= 6 ）or peripheral type （n= 1 3 ）;oval or irregular shape with lobular （n= 13）or spicular sign （n= 5）;the diameter was 3--7cm,mean （4.60±1.99）cm;necrosis （n= 7）,haemorrhage （n= 2） or calcification （n= 1 ）;the secondary changes including pleural indentation （n= 3 ）,obstructive pneumonia and atelectasis （n= 2）,pleural effusion （n= 4）,hilar and mediastinal lymphadenectasis （n= 9）and distant metastasis.Conclusion：LCNECs have no characteristic features on CT,and the final diagnosis must depend on clinical data and pathologic examination.
