摘　　要：目的:分析高分化胰腺神经内分泌肿瘤的CT征象并与病理对照分析,以期提高该病的诊断及鉴别诊断水平。方法:回顾性分析18例经手术病理证实的高分化胰腺神经内分泌肿瘤患者的资料,分析其CT特征。结果:18例病人共检出18个病灶,均为单发病灶,边界清楚,包膜完整。胰头部7例,胰颈部4例,胰体部1例,胰尾部6例;其中实性肿瘤12个,增强后动脉期明显或中度强化,门脉期4个持续强化,8个门脉期强化程度减低,但仍高于胰腺实质;囊实性肿瘤6个,3个病灶增强后不均匀强化,1个病灶增强后分隔强化,1个囊性为主型病灶环形强化,囊变区无强化,1个病灶薄壁环形强化。结论:高分化胰腺神经内分泌肿瘤的CT表现具有一定特征性,CT有助于术前诊断及分期。Purpose：To analyze the diagnostic value of of well-differentiated pancreatic neuroendocrine tumors and compare the CT features with pathology results to improve the diagnostic and differential diagnostic level.Methods：Eighteen cases with pathologically proved well-differentiated pancreatic neuroendocrine tumors were retrospectively analyzed.The CT features were studied.Results：Of the 18 cases,18 lesions were revealed,all cases showed single lesion with clear margin and intact capsule.Seven of them were localized in the pancreatic head,4 in the neck,1 in the body,and 6 in the tail.Twelve cases were showed as completely solid mass,marked or moderate enhancement of the tumors could be seen in arterial phase,4 cases of them were showed with continuous enhancement in venous phase,8 cases were showed with declined enhancement in venous phase,but higher than normal pancreas.Six cases were cystic and solid mass,3 cases of them were showed with inhomogenous enhancement,1 case was showed with septal enhancement,ring-enhancement was seen in one mainly cystic mass,while cystic areas had no enhancement,marked thin-wall enhancement was seen in one case.Conclusion：Certain CT characteristics could be revealed in well-differentiated pancreatic neuroendocrine tumors,and is useful for the diagnosis and staging of them before surgery.
