【摘要】 目的:探讨胰腺炎并发假性动脉瘤的CT征象及诊断中的价值。材料与方法:回顾性分析经手术证实的胰腺炎并发脾动脉假性动脉瘤患者的CT征象、发生部位及发生的原因等。结果:胰腺炎并发脾动脉假性动脉瘤,胰腺体尾部增大,其可见类圆形低密度灶,内密度不均匀,边缘清楚,后缘可见短条状钙化斑。双期增强扫描示胰腺体尾部后上方见6.7 cm×5.8 cm×5.4 cm的病灶部分呈团样强化,脾动脉前缘与团样强化灶分不清,在动、门静脉期时CT值均与同层面腹主动脉CT值一致,其余部分强化不明显,且呈略低密度(图1~2),可能有血栓。结论:增强扫描在胰腺炎并发假性动脉瘤的诊断中有很重要价值。更多还原

【Abstract】 Purpose:Pancreatitis concurrent pseudoaneurysms CT signs and the diagnostic value of.Materials and Methods:Retrospective analysis of operation confirmed pancreatitis concurrent splenic artery pseudoaneurysms patients CT signs,location and occurrence is the main reason,etc.Results:Pancreatitis concurrent splenic artery pseudoaneurysms,pancreatic body tail increases,visibility of circular low density kitchen,the density uneven edges clear,edge visible short strip calcified plaque.Double period enhance scan after sheba pancreas body tail above see 6.7 cm x 5.8 cm x 5.4 cm lesions in regiment sample strengthening,partial splenic artery front and focal points strengthening group samples not clear,moving,portal period when CT value are with level abdominal aortic CT value consistent,and the rest of the aggrandizement is not apparent,and a slightly low density(figure 1~2),may have a blood clots.Conclusion:Contrast-enhaneed CT scans were of great importance in the diagnosis of pseudoaneurysm complicating pancreatitis.更多还原
