摘要
目的提高对中央型未分化小细胞肺癌多层螺旋CT(MSCT)特征的认识。方法回顾性分析21例中央型未分化小细胞肺癌(研究组)的MSCT平扫、动态增强资料,同期80例中央型肺鳞癌为对照组,探讨中央型未分化小细胞肺癌的MSCT特征。结果中央型未分化小细胞肺癌的MSCT表现特征是:支气管管腔虽有狭窄但尚通畅,肿瘤长轴方向与相应支气管走行一致,常转移到上腔静脉后、主动脉弓下和隆突下淋巴结,常有远处转移,这些征象的出现率高于对照组(P<0.05)。结论 MSCT征象有助于中央型未分化小细胞肺癌的诊断及鉴别诊断。
Objective To further recognize multi-slice spiral CT （MSCT） imaging feature of central undifferentiated small cell lung carcinoma（cSCLC）.Methods A retrospective case-control study involved in MSCT information of 21 patients with central undifferentiated SCLC（study group）, and 80 patients（control group）with squamous carcinoma at the same time, were performed to find out MSCT imaging feature of cSCLC.Results The following features were found in cSCLC： infiltrated bronchus unobstructed, the long axis of carcinoma being parallel to the infiltrated bronchus, metastatic lymph nodes in the area of posterior of superior vena cava（SVC）, subaortic and subcarinal, and other metastases. The incidence of these features was significantly higher in study group than in control group（P0.05）.Conclusions MSCT imaging features were helpful to diagnose and differentially diagnose cSCLC.
