多层螺旋 CT 在小细胞肺癌诊断中的价值

Value of MSCT in the diagnosis of small cell lung cancer

目的:探讨多层螺旋CT(MSCT)在SCLC诊断中的价值。方法:搜集经病理证实的50例SCLC患者的资料,详细分析其CT表现。结果:48例表现为局部结节或肿块,38例出现分叶状,6例出现钙化,6例出现胸膜凹陷征,14例出现磨玻璃影,34例出现阻塞性肺炎,30例出现阻塞性肺不张,28例出现胸腔积液,38例出现肺门淋巴结肿大,44例出现纵隔淋巴结肿大,20例出现"冰冻纵隔",17例伴远处转移。结论:SCLC在CT表现上具有一定的特征性,最终确诊需结合临床病理。

Objective：To study the value of MSCT in the diagnosis of small cell lung cancer （SCLC）.Methods：The imaging of 50 cases of pathology proved SCLC were recruited and their CT features were analyzed in detail.Results：Of the 50 patients,there were focal mass or nodule （48 cases）,which were lobular （38 cases）and 6 cases with calcification,6 cases with pleural indentation,14 cases with ground-glass opacity.34 cases were accompanied with obstructive pneumonia and 30 cases with atelectasis.28 cases had pleural effusion.38 cases accompanied with hilar lymph adenopathy,44 cases with medi-astinal lymph adenopathy,20 cases with frozen-mediastinum.17 cases had distant metastasis.Conclusion：Certain CT charac-teristics could be assessed in SCLC,yet the final diagnosis still depends on pathology.
