_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。
_目的：通過分析縱隔神經內分泌癌的 CT 錶現，提高對此病的認識和診斷準確性。方法：迴顧性分析經病理證實的11例縱隔神經內分泌癌的 CT 錶現。結果：11例中腫瘤位于前縱隔4例，位于後縱隔1例，其餘6例全部位于前中縱隔。11例腫瘤呈類圓形2例，形態不規則7例，2例邊緣有輕度分葉。平掃腫瘤均呈實性密度，其中9例密度不均勻，伴有不同範圍的壞死囊變；11例中7例有鈣化錶現，以點狀及片狀多見；註射對比劑後，均呈不均勻彊化，11例中3例錶現為明顯彊化，其餘8例均為輕中度彊化；11例中除1例髮生于後縱隔者，其餘10例均有壓迫或侵犯鄰近縱隔結構的錶現。結論：縱隔神經內分泌癌的 CT 錶現有一定特徵性，CT 對本病的診斷和術前評估具有重要意義。

_ 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.
