目的：探讨肺内神经内分泌癌的CT表现。方法回顾性分析经病理证实42例肺内神经内分泌癌的CT征象并进行分析。结果1.发病部位：中央型30例(左肺20例，右肺10例)，周围型12例(左肺6例，右肺6例)。中央型和周围型神经内分泌癌在发病部位分布上差异无统计学意义(X2=11.086，P=0.086)。2.影像学特征，肺内神经内分泌癌多呈分叶状，密度可以均匀或不均匀，气管阻塞伴阻塞性肺炎、肺不张，淋巴结转移常见。肺内周围型神经内分泌癌与中央型神经内分泌癌在影像学表现差异无统计学意义(P>0.05)。3.肺内神经内分泌癌病理类型与淋巴结转移差异有统计学意义(P<0.0001)；大细胞型神经内分泌癌和小细胞肺癌(P=0.0008)及小细胞肺癌和类癌(P=0.0023)分布差异有统计学意义。结论肺内神经内分泌癌以中央型多见，多呈分叶状，伴阻塞性肺炎、肺不张，易出现淋巴结转移。

Obective To study the CT features of the pulmonary nenroendocrine carcinoma.Methods CT data of 42 patients with histologically confirmed pulmonary neuroendocrine carcinoma were retrospectively analyzed.Results 1. Location 30 patients is central type wich20 patients in left lung,10 patients in right lung; 12 patients is peripheral type(6 patients in left lung and 6 patients in right lung ). The location distribution between central type and peripheral type neuroendocrine carcinoma in lung has no statistically significant difference(X2=11.086, P=0.086). 2. Imaging features the desity of neuroendocrine carcinoma may be homogeneous or heterogeneous; most lesions are lobulated with bronchial obstructive and pneumonia, lymphatic metastases are often seen .The imaging features of the central type and peripheral type neuroendocrine carcinoma have no statistically significant difference(P>0.05). 3. Lymphatic metastases in different pathological types have statistically significant difference ; lymphatic metastases in large cell neuroendocrine carcinoma and small lung cancer (P=0.0008) and small lung cancer and Carcinoid (P=0.0023) statistically significant difference.Conclusion Nenroendocrine carcinoma most are central type. Most lesions are lobulated with bronchial obstructive and pneumonia, lymphatic metastases are often seen.
