胸腺瘤的CT诊断

CT Diagnosis of Thymoma

目的：探讨胸腺瘤的ＣＴ诊断价值。资料和方法：胸腺瘤１７例，均经手术病理证实，其中６例仅作平扫，１１例平扫加增强扫描。结果：非侵袭性胸腺瘤７例，侵袭性胸腺瘤１０例，ＣＴ对两者的鉴别主要根据肿瘤的大小、边缘，肿瘤与心脏大血管的接触面、两者所成角度及其间的脂肪影，以及胸膜和心包改变。结论：ＣＴ对判断胸腺瘤是否为侵袭性有重要作用，为临床制定治疗计划，估计预后提供重要依据。

s Purpose:To study the value of CT diagnosis of thymoma.Materials and Methods:17 cases with thymoma verified by operation and pathological study,6 cases with plain scanning and 11 cases with both plain and enhanced scanning.Result:10 cases were invasive thymoma,7 cases non invasive.CT differential diagnosis between the two types of thymoma is mainly based on the size and margin of the thymoma,the contact area,angle and fat shadow between thymoma and heart,surrounding large vessels,and the changes of pericardium and pleura.Conclusion:CT plays an important role in determing whether thymoma is invasive or not and providing more informations for making the treatment plan and evaluating the prognosis.
