摘　　要：目的探讨前纵隔淋巴瘤误诊为侵袭性胸腺瘤的原因并就此分析两者的鉴别点。方法回顾性分析本院收治的2例前纵隔淋巴瘤误诊为侵袭性胸腺瘤的病例资料并查阅相关文献。结果侵袭性胸腺瘤和前纵隔淋巴瘤均是前纵隔常见肿瘤,两者的鉴别诊断主要是从患者的发病年龄、临床表现及肿瘤生长部位、形态边缘、密度、强化方式、同邻近心脏大血管的关系、有无邻近结构侵犯几个方面进行分析。结论前纵隔淋巴瘤和侵袭性胸腺瘤各自具备一定的影像特征,诊断时必须仔细并密切结合临床。Objective To investigate the causes of anterior mediastinal lymphoma misdiagnosed as invasive thymoma and analyze their differential points.Methods:The clinical and imaging data of two cases of anterior mediastinal lymphoma misdiagnosed as invasive thymoma in our hospital were analyzed retrospectively and the related literature was reviewed as well.Results: Invasive thymoma and anterior mediastinal lymphoma are common tumors in the anterior mediastinum. The differential diagnosis of the two tumors is mainly considered from the age of onset,clinical manifestations,tumor location,morphology and margin,density, enhancement mode, relationship with adjacent heart and large vessels, and the presence or absence of adjacent structure invasion.Conclusion:Anterior mediastinal lymphoma and invasive thymoma have some imaging manifestations respectively. Based on the combination of their imaging features and the clinical information, the diagnosis can be made correctly.
