中文摘要:
      目的 比较浸润与无浸润生长胰腺实性假乳头状瘤(SPTP)的MRI表现。方法 回顾性分析经手术病理证实的浸润生长SPTP患者20例(浸润组)和无浸润生长SPTP患者26例(无浸润组)的平扫及动态增强MRI特点。结果 浸润与无浸润组患者性别、年龄、病灶位置、病灶大小、类型、延迟期强化类型差异均无统计学意义(P均>0.05),而病灶形态、周围侵犯情况差异有统计学意义(P均<0.05)。结论 SPTP形态不规则及侵犯周围组织时,提示恶性可能。即使病灶<30 mm且无周围侵犯征象,也不能排除肿瘤浸润。
英文摘要:
      Objective To compare MRI features of invasive and non-invasive solid pseudopapillary tumor of the pancreas (SPTP).Methods Forty-six SPTP patients confirmed by surgery and pathology, including 20 invasive SPTP (invasion group) and 26 non-invasion SPTP (non-invasion group) underwent convention and dynamic contrast-enhanced MR, and then MRI features and clinical data of SPTP patients were retrospectively analyzed and compared between the two groups.Results There was no significant difference of patients gender and age, tumor's location, size, types nor enhancement types of delay phase between the two groups (all P>0.05), while there were significant differences of tumor's shape and adjacent invasion between the two groups (both P<0.05).Conclusion MRI findings of SPTP with irregular shape and adjacent infiltration may indicate the possibility of malignancy. MRI findings of SPTP with diameter <30 mm and no adjacent invasion cannot exclude tumor infiltration.
