目的 探讨胰腺实性假乳头状瘤(SPTP)的CT表现特点，提高诊断水平。方法 回顾性分析经病理证实的9例SPTP的CT 表现，其中男1例，女8例；年龄10-52岁，平均年龄32岁，所有病例均行CT平扫及多期动态增强检查。结果 肿瘤 位于胰尾6例，胰头2例，胰体1例。8例呈类圆形，1例呈不规则分叶状，肿瘤最大径为4.7-12cm，平均为6.8cm。6 例SPTP呈囊实性，2例呈囊性，1例呈实性。4例SPTP的CT扫描见出血征象；6例可见钙化，5例边缘斑点、斑片状钙 化，1例呈环壁蛋壳状钙化。增强扫描动脉期肿瘤实性部分轻度强化，门静脉期呈明显强化，呈渐进性向心性强化 特点。结论 SPTP的CT表现具有一定特征，结合临床特点可以做出诊断。

Objective To study the MSCT findings of solid pseudopapillary tumors of the pancreas(SPTP), in order to improve the diagnostic level. Methods The findings of MSCT imaging in 9 cases with pathologically proved SPTP were analyzed retrospectively. One patient was male, 8 patients were female, age from 10 to 52 years old, with average of 32 years old. All patients were underwent CT plain scans and multiple phase enhanced scans. Results 6 tumors were located in tail of pancreas,2 in head and 1 in body. 8 lesions were oval and 1 lesion was lobular, with the diameter ranging from 4.7 to 12.0 cm (mean 6.8cm). 6 cases were solid-cystic tumors, 2 cases were cystic tumors and 1 was pure solid tumor. Hemorrhages were seen in 4 cases on CT images. Calcification were seen in 6 cases, with patchy calcification around in 5 cases, and eggshell calcification in l case. The solid part of the tumors were enhanced slightly in the arterial phase and markedly in the portal venous phase, presenting gradual and central enhancement. Conclusion There are some characteristics on MSCT findings of SPTP. The correct imaging diagnosis is possible based on clinical characteristic and CT findings.
