胸腺瘤临床特点的病例对照研究

The Case-control Study on Clinical Features of Thymoma

目的探讨胸腺瘤临床特点及影像学特征。方法选取经病理确诊胸腺瘤42例为胸腺瘤组,按1∶1配比选取42例纵隔非胸腺瘤病变住院患者为对照组,分析两组临床特点及影像学特征的异同。结果胸腺瘤组眼睑下垂发生率、外周血淋巴细胞计数降低率显著高于对照组,影像学上胸腺瘤主要位于上前纵隔,且边缘不光滑。结论眼脸下垂、外周血淋巴细胞计数低,影像学上病变位于前上纵隔、边缘不光滑的纵隔病变,胸腺瘤可能性大。

Objective To summarize the clinical features and imaging characteristic of thymoma.Methods 42 patients with thymoma were choosed as case group and 42 patients with other space-occupying mass in mediastinum as control group,through 1∶1 matched case-control study,the difference of clinical features and imaging characteristic were analyzed between case and control group.Results The incidence of blepharoptosis and low contents of peripheral-blood lymphocytes of case group was more frequent than that of control group.Thymoma mainly situateed upper and frond position of mediastinum and had indistinct border.Conclusion The mass which has features of blepharoptosis,low contents of peripheral-blood lymphocytes,situating upper and frond position of mediastinum and indistinct border is probably thymoma.
