【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。更多还原

【Abstract】 Objective:To explore the diagnostic value of MSCT in large cell neuroendocrine carcinoma(LCNEC).Methods:The clinical and CT data of 19 patients with LCNEC confirmed by pathology were analyzed retrospectively.Results:The main CT findings of LCNEC:central type(n=6)or peripheral type(n=13);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.更多还原
