摘　　要：目的:通过分析纵隔神经内分泌癌的CT表现,提高对此病的认识和诊断准确性。方法:回顾性分析经病理证实的11例纵隔神经内分泌癌的CT表现。结果:11例中肿瘤位于前纵隔4例,位于后纵隔1例,其余6例全部位于前中纵隔。11例肿瘤呈类圆形2例,形态不规则7例,2例边缘有轻度分叶。平扫肿瘤均呈实性密度,其中9例密度不均匀,伴有不同范围的坏死囊变;11例中7例有钙化表现,以点状及片状多见;注射对比剂后,均呈不均匀强化,11例中3例表现为明显强化,其余8例均为轻中度强化;11例中除1例发生于后纵隔者,其余10例均有压迫或侵犯邻近纵隔结构的表现。结论:纵隔神经内分泌癌的CT表现有一定特征性,CT对本病的诊断和术前评估具有重要意义。Objective：To analyze the CT findings of neuroendocrine carcinoma of mediastinum,in order to raise awareness of the disease and improve the diagnostic accuracy.Methods：A retrospective analysis of CT findings of 11 cases of pathologically confirmed neuroendocrine carcinoma of mediastinum were performed.Results：Of the 11 cases,4 were loca-ted in anterior mediastinum,1 case was located in posterior mediastinum,and the remaining 6 cases were located in the mid-dle mediastinum.two of the 11 cases were round in shape,2 cases were with mild lobulated edges and 7 cases had irregular shapes.All 11 cases had solid density,of which 9 cases were with heterogeneous density and showed cystic degeneration. Punctate and flaky calcifications were found in 7 of 11 lesions.After injecting contrast medium,3 cases showed marked en-hancement,others showed slight to moderate enhancement.All 11 cases showed heterogeneous enhancement.Except the one in the posterior mediastinum,all other 10 lesions were invading or compressing mediastinal structures.Conclusion：Neuroen-docrine carcinoma of mediastinum has characteristics on CT images,which has great significance for clinical diagnosis and surgical planning.
