摘要 目的探讨胰腺实性假乳头状瘤(SPT)的螺旋CT表现,以提高对该病的认识。方法回顾性分析复旦大学附属中山医院收治且经手术及病理证实的38例SPT患者的病历资料,总结SPT在螺旋CT上的特征性表现。结果 38例患者中,女35例,男3例,共39个病灶(1例为胰头、胰尾各1个病灶),其中囊实性36个(92.3%),实性3个(7.7%);胰体部、胰尾部各13个(各33.3%),胰颈部7个(17.9%),胰头部6个(15.4%)。36例(94.7%)病灶包膜完整,与胰腺实质分界清晰;2例(5.3%)病灶局部与胰腺组织分界不清,其中1例伴肝脏转移。11个(28.2%)病变内可见钙化。三期增强扫描呈渐进性强化:动脉期实性部分轻度强化,门脉期、延迟期进一步强化,但病变实性部分强化低于正常胰腺组织。本组1例(2.6%)肝内见相似强化结节灶,余病例胆总管、胰腺管均未见扩张,后腹膜未见肿大淋巴结。结论 SPT的MDCT表现有一定特征性,术前CT检查对SPT有重要的诊断价值。
