目的探讨胃肠道神经内分泌肿瘤的CT表现与病理分类关系. 方法回顾性分析54例胃肠道神经内分泌肿瘤患者的CT资料,分析其影像特点并与病理进行对照. 结果 22例患者为高分化神经内分泌肿瘤,32例为低分化神经内分泌肿瘤. 肿瘤直径(>3cm)、肿瘤经壁侵犯、坏死囊变、邻近组织侵犯、淋巴结转移高分化神经内分泌肿瘤、低分化神经内分泌肿瘤两组间差异有显著性(P<0. 05). 肿瘤边界、生长方式、增强程度、远处转移在两组间差异无显著性(P>0. 05). 结论 CT有助于神经内分泌肿瘤病理分级.

Objective To study correlation between the CT features and pathologic classification of gastrointestinal neuroendocrine neoplasms ( GE-NENs) . Method CT imagings of 54 GE-NENs patients confirmed by histopathology were retrospectively analyzed. Correlation of these imagings findings with pathologic classification was studied. Result Fifty-four cases of GE-NENs included 22 cases of neuroendocrine tumors ( NETs) and 32 cases of neuroen-docrine carcinomas ( NECs ) . The CT features were significant difference between the two groups including lager tumor size, transmural invasion, areas of cystic changes or necrosis, adjacent organ invasion and lymphadenopathy (P<0. 05). There was no difference between the two types of GE-NENs including tumor boundary, grown pattern, degree of enhancement and distant organ metastasis (P>0. 05). Conclusion CT can be useful for the pathologic classification of GE-NENs.
