摘　　要：目的　探讨肺大细胞神经内分泌癌的CT表现。方法　回顾性分析 13例病理证实的肺大细胞神经内分泌癌的螺旋CT表现。 3例病灶区加扫薄层 ;4例增强扫描。结果　肿瘤呈周围型 (7例 )、中央型 (4例 )及纵隔型 (2例 ) ;周围型边缘光整锐利 ,伴浅分叶 ;中央型伴阻塞性肺炎及肺不张 ;增强后呈中等强化。 1例出现纵隔内淋巴结肿大。未见钙化及空洞。结论　肺大细胞神经内分泌癌CT表现无明显特征 。Objective To study the CT diagnosis in large cell neuroendocrine carcinoma of the lung (LCNEC). Methods CT findings of 13 patients with LCNEC confirmed by surgery or bronchoscopy were retrospectively analyzed. All of them were examined by spiral CT, 3 cases by thin-sectional CT scan and 4 cases by enhanced CT scan. Results The lesions were presented as peripherial (7 cases),central (4 cases) and mediastinal (2 cases) pattern. The sizes of peripherial lesions were from 1.9 to 8.0 cm, of central lesions were from 2.2 to 3.5 cm. Peripherial lesions were oval or round well demarcation masses with lightly lobulated margin, meanwhile the lesions of central pattern presented as distal atelectasis and obstructive pneumonia. On enhanced CT, 4 lesions showed moderate enhancement. One case had mediastinal lymphadenopathy. Neither calcification nor cavity was observed in all the 13 patients. Conclusion CT findings of LCNEC of the lung are nonspecific. Pathological examination is necessary for the diagnosis of LCNEC.
