摘　　要：目的总结分析纵隔神经内分泌癌的CT表现,提高诊断准确性。方法回顾性分析20例经手术病理证实的纵隔神经内分泌癌的临床资料及CT表现。结果纵隔神经内分泌癌的患者多无明显特殊临床症状,50%有胸闷、咳嗽,平均年龄(56.9±10.32)岁,17例发生在前纵隔,均为单发,平均直径(6.3±2.4)cm,19例呈分叶状或结节状,3例见点状钙化,20例均出现液化坏死,平均强化幅度为(29.7±11.65)HU。结论纵隔神经内分泌癌术前诊断困难,临床表现及CT表现均无明显特异性,但当病变位于前上纵隔偏左侧伴多发小灶样坏死时,应考虑到该病的可能。Objective Combining with the cases and the literature, we summarized mediastinal CT manifestation of neuroen- doerine carcinoma so as to improve the diagnostic accuracy. Methods We retrospectively analysed of 20 cases with mediastinal neuroendocrine carcinoma, which was confirmed by pathology, analysed clinical data and CT manifestations of 20 cases. Results Mediastinal neuroendoerine carcinoma patients presented with no obvious special clinical symptoms, 50% with chest tightness, cough. The average age was 57 years old, the sex ratio was 5.7：1. 17 cases occurred in the anterior mediastinum which were all single, with average diameter of （6.3 ± 2.4） cm. 19 cases were nodular or lobulated, 3 cases presented with punctate calcification, 20 eases with liquefaction necrosis. The average reinforcement range was （29.7±11.65 ） HU. Conclusion Preoperative diagnosis of mediastinal meuroendocrine carcinoma is difficult, clinical manifestation and CT show no obvious specificity, but when mediastinal lesions located in the former partial left with the muhifocal necrosis, consideration should be given to the possi- bility of the disease.
