目的探讨胰腺实性假乳头状瘤 (SPTP)的CT与MRI诊断及良性SPTP与SPC的 鉴别诊断。方法 回顾性分析经病理证实 的58例SPTP资料。结果 患者的年龄、性 别、发病部位及钙化在良性SPTP与SPC之 间的差异无统计学意义，肿瘤边界、形态 及大小在良性SPTP与SPC之间的差异有统 计学意义。结论 胰腺实性假乳头状瘤的 CT与MRI诊断及良性SPTP与SPC的鉴别诊断 具有一定的特征性。

Objective To investigate the CT and MRI diagnosis of solid-pseudopapillary tumor of the pancreas (SPTP) and the diifferential diagnosis of benign SPTP and SPC. Methods The data of 58 cases SPTP proved by pathology were analyzed retrospectively. Results There was no significant difference in gender,age,site of disease,calcification in benign SPTP and SPC,the difference was statistically significant in the tumor boundary, the shape and the size in benign SPTP and SPC. Conclusion The CT and MRI diagnosis of SPTP and the differential diagnosis of benign SPTP and SPC have certain characteristics.
