摘　　要：胰腺神经内分泌肿瘤（pNENs）是一组具有潜在恶性的少见肿瘤,依据临床有无内分泌症状分为功能性和非功能性两类.MRI检查有助于非功能性pNENs的术前诊断.本研究回顾性分析2010年3月至2014年2月解放军总医院收治的22例非功能性pNENs患者的临床资料.其结果显示：MRI动态增强扫描示肿瘤呈持续或渐进性中度至明显强化、肿瘤周边包膜中度至明显强化是非功能性pNENs的特征性表现,突破包膜生长或明显分叶样生长改变提示肿瘤可能具有局部侵袭性生长趋势.该特征对该类肿瘤的诊断与鉴别诊断具有重要价值.Pancreatic neuroendocrine neoplasms （pNENs） are rare tumors with malignant potential.The pNENs could be classified into functional or nonfunctional according to associated clinical symptoms.Magnetic resonance imaging （MRI） is helpful for preoperative diagnosis of nonfunctional pNENs.The clinical data of 22 patients with nonfunctional pNENs who were admitted to the Chinese PLA General Hospital from March 2010 to February 2014 were analyzed retrospectively.Nonfunctional pNENs were characterized by moderate to marked,consistent or progressive enhancement with capsule-like enhancement on dynamic contrast MRI,which is very important for the diagnosis and differential diagnosis of pNENs.
