Abstract: Objective To evaluate the diagnostic value of MSCT in peripheral pulmonary neuroendocrine carcinoma.Methods CT findings of 42 peripheral pulmonary neuroendocrine carcinoma confirmed pathologically were compared among different pathological types.Results As for lymphatic metastases,small cell carcinoma was more commom than other pathological types(P＜0.05).Most of peripheral pulmonary neuroendocrine carcinoma had homogeneous density(29 cases) and was lobulated(30 cases).The specula sign,vessel convergence sign,pleural indentation sign and obstructive pneumonia in this group were rare(8 cases,4 cases,7 cases,8 cases respectively).Most lesions had enhancement lightly.CT values of the lesions and the enhanced degree were similar in different pathological types and there was no difference among them(P＞0.05).Conclusion msct is of definitive value in diagnosis or differentitating diagnosis in the different pathological types of peripheral pulmonary neuroendocrine carcinoma.
