摘　　要：目的:探讨肺神经内分泌癌临床特征及CT表现。方法:回顾分析四川大学华西医院2008年-2010年间收治的27例经病理或手术确诊的肺神经内分泌癌患者的临床及影像学资料,全部病例均行MDCT平扫及增强扫描。结果:肺神经内分泌肿瘤临床主要表现为发热、咳痰、咳嗽、胸背痛、痰中带血。右肺14例,左肺13例,中央型15例,周围型10例。最大约10cm-11cm,最小约1cm。影像表现为局部结节或肿块影,7例伴有肺不张和阻塞性炎症,9例肺门淋巴结增大,12例纵膈淋巴结增大,10例胸腔积液,6例心包积液,9例远处转移。结论:肺神经内分泌癌临床及影像表现缺乏特异性,其诊断仍需结合临床及病理。Objective：To explore CT features of pulmonary neuroendocrjne tumor. Methods： Imaging findings of 27 patients with pathologically or surgery confirmed pulmonary neuroendocrjne tumor in Huaxi Hospital, Sichuan Univercity from 2008 to 2010 were retrospectively analyzed, all patients underwent plain CT and contrast enhanced CT examinations. Results： Pulmonary neuroendoerjne tumor usually has symptoms such as fever, expectoration, chest and back pain, blood sputum. There were 14 cases at right lung, 13 cases at left lung, 15 eases at central area and 10 cases at peripheral area.
