摘　　要：目的探讨胰腺实性假乳头状瘤(SPT)的MRI表现及外科治疗,提高对本病的认识及诊断水平。资料与方法回顾性分析解放军总医院经外科手术切除并经病理确诊的30例SPT患者的临床及MRI资料。结果 30例患者病灶部位:胰头部8例(26.7%),胰颈部3例(10.0%),胰体部8例(26.7%),胰尾部7例(23.3%),胰体尾部4例(13.3%)。瘤体成分:囊实性21例(70.0%),实性6例(20.0%),囊性3例(10.0%)。25例(83.3%)见假包膜;2例(6.7%)伴胰管扩张。动态增强特征表现为实性部分渐进性强化。采用传统外科手术或机器人手术,手术切除后随访6~18个月均无肿瘤复发。结论胰腺SPT的特异性MRI表现包括有假包膜、渐进性强化的囊实性肿块,手术切除预后良好。Purpose To discuss the MRI features of solid pseudopapillary tumor(SPT)and surgical treatment,to improve the understanding and diagnosis of SPT.Materials and Methods Clinical and MRI data of 30 patients with SPT surgically removed and pathologically confirmed in PLA General Hospital were analyzed retrospectively.Results All the 30 patients were surgically removed.The lesions located in the pancreatic head,neck,body,tail,body and tail were 8 cases(26.7%),3 cases(10.0%),8 cases(26.7%),7 cases(23.3%),4 cases(13.3%),respectively.SPTs were classified as cystic and solid 21 cases(70.0%),purely solid 6 cases(20.0%),purely cystic 3 cases(10.0%).25 cases(83.3%)with pseudocapsule.2 cases(6.7%)with pancreatic duct expansion.The solid part showed progressive enhancement in dynamic enhanced scan.Surgical methods include traditional surgery and robotic surgery.All patients were followed up for 6 to 18 months,no tumor was recurrence.Conclusion The specific imaging features of SPT in pancreas are cystic and solid masses with pseudocapsule,progressive enhancement,surgery operation has a good prognosis.
