摘要 目的探讨胰腺神经内分泌肿瘤(pancreatic neuroendocrine tumors,PNET)的影像学表现与病理分级的相关性,提高术前诊断准确性。方法回顾性收集浙江省肿瘤医院2016年5月至2021年4月22例经手术病理证实为PNET患者的CT或者MRI图像和病理资料。结果22例患者共有24个病灶,其中2例(9%)2个病灶,其余20例(91%)单发病灶。病灶部位:胰头6个,胰体10个,胰尾8个。病理类型:囊实性5个(21%),实性19个(79%),伴钙化4个(17%);病理分级:G1级10个(42%),G2级12个(50%),G3级2个(8%)。结论G1级病灶体积大、囊变更多见(40%),边界清,强化明显;G2级病灶边界可清可不清,囊变少见,强化程度相对低,可出现肝脏转移;G3级病灶强化程度低,恶性程度高,对周围结构侵犯明显,可出现远处转移,不同病理分级的PNET影像上有相应的特征性表现。
