多层螺旋CT在周围型肺神经内分泌癌的诊断价值

目的 探讨不同类型周围型肺神经内分泌癌的MSCT征象及诊断价值.方法 对具有完整胸部MSCT资料并经病理学证实的42例周围型肺神经内分泌癌CT表现进行比较分析.结果小细胞癌与其他类型神经内分泌癌在淋巴结转移方面有显著性差异(P<0.05).不同病理类型的周围型肺神经内分泌癌病灶密度多较均匀(29例),多有分叶(30例);病灶毛刺征,血管集束征,胸膜凹陷征和周围阻塞性肺炎在本组少见(分别为8例,4例,7例,8例);病灶呈轻度强化,病灶密度值、强化程度相仿,以上征象均无统计学差异(P>0.05).结论 MSCT对不同周围型肺神经内分泌癌的诊断和鉴别诊断有一定价值.

Peripheral Pulmonary Neuroendocrine Carcinoma:Multi-slice Spiral CT Diagnosis

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.
