目的:探讨肺小细胞神经分泌癌的MDCT表现特征。方法:对具有完整胸部MDCT资料并经病理证实的28例肺小细胞神经内分泌癌CT表现进行回顾性分析。结果:中央型肺小细胞神经内分泌癌18例(64%),支气管管壁增厚伴肺内肿块或结节17例(94%),纵隔或肺门淋巴结肿大15例(83%),增强扫描可见肿块与肿大淋巴结明显不均匀强化,周围型肺小细胞神经内分泌癌10例(36%),密度均匀,呈分叶状,强化明显,CT无特征性表现。结论:肺小细胞神经内分泌癌主要征象以支气管管壁增厚伴肺门区肿块为主,多伴有肺门、纵膈淋巴结转移。
Objective: To investigate the characteristics of MDCT in small cell neuroendocrine carcinoma of the lung. Methods: The CT findings of 28 cases of pulmonary neuroendocrine carcinoma with complete chest MDCT confirmed by pathology were retrospectively analyzed. Results: Central pulmonary small cell neuroendocrine carcinoma was found in 18 cases (64%), bronchial wall thickening with pulmonary masses or nodules in 17 cases (94%), mediastinal or hilar lymphadenopathy in 15 cases (83%), Enhanced scan visible masses and enlarged lymph nodes were significantly uneven enhancement, peripheral pulmonary small cell neuroendocrine carcinoma in 10 patients (36%), uniform density, lobulated, enhanced obviously, CT no specific performance. Conclusions: The main signs of pulmonary small cell neuroendocrine carcinoma are mainly bronchial wall thickening and hilar mass, which are often associated with hilar and mediastinal lymph node metastasis.
