摘　　要：目的:分析胰腺实性假乳头状瘤(SPTP)的CT、MRI表现,以提高对该病的诊断水平。方法:3例患者均为女性,经手术和病理证实为SPTP,术前均接受CT检查,其中1例患者接受MRI检查。结果:3例患者CT表现为胰腺内囊实性占位,均无胆管扩张,其中1例在肿瘤的实性成分内可见钙化灶。MRI T1WI和T2WI上均为混杂信号。CT和MRI增强均显示囊壁及肿瘤的实性成分有明显强化。结论:SPTP的影像学表现具有一定特征性,可为临床诊断提供帮助。Objective： To investigate the CT and MRI findings of solid-pseudopapillary tumors of the pancreas （ SPTP）, and to improve the diagnosis of the disease. Methods ： Three female SPTP patients received CT examination, 1 of them underwent MRI in addition, and all the cases were surgically and pathologically confirmed later. Results： CT images revealed huge solid-cystic mass in the pancreas of the 3 patients, 1 with calcification in the mass and all without dilation of the bile duct. MRI exhibited mixed signal intensity on TIWI and T2WI. Both CT and MRI showed obvious enhancement of the cystic wall and the solid part of the mass. Conclusion： SPTP has its characteristic imaging manifestations, which may contribute a lot to the diagnosis of the disease.
