目的探讨CT对胰腺实性—假乳头状瘤的诊断与鉴别诊断依据。方法回顾性分析经手术及病理证实的11例胰腺实性—假乳头状瘤的CT表现。结果 11例病灶中,囊性结构为主7例,囊、实结构比例相仿3例,实性结构为主1例。CT平扫病灶呈类圆形低密度团块影;增强扫描,实性部分明显强化,囊性部分各期均无强化。结论胰腺实性—假乳头状瘤CT表现具有一定特征性,可对其做出诊断与鉴别诊断。
Objective To investigate the diagnosis and differential diagnosis of solid pancreatic pseudopapillary tumor by CT. Methods The CT findings of 11 cases of solid-pseudopapillary pancreatic tumors confirmed by surgery and pathology were retrospectively analyzed. Results Of the 11 lesions, cystic structures were mainly found in 7 cases. The proportion of capsule and solid structure was similar in 3 cases and the solid structure was mainly in 1 case. CT plain lesions showed a round low-density mass shadow; enhanced scan, the solid part was significantly enhanced, cystic part of the non-intensified. Conclusion The CT manifestations of pancreatic solid-pseudopapillary tumor have certain characteristics, which can make diagnosis and differential diagnosis.
