纵隔异位胰腺的影像诊断及其临床表现——附2例报告并文献复习

Imaging diagnosis and clinical findings of ectopic pancreas in mediasti-num:two cases report and review of the literature

目的探讨纵隔异位胰腺的影像诊断要点。方法搜集2例经手术病理证实的纵隔异位胰腺的病例,回顾分析其影像及临床表现。结果2例异位胰腺均位于右侧前中下纵隔,其影像表现类似纵隔囊肿,病灶巨大。患者无特异性临床表现。结论纵隔异位胰腺罕见,其影像表现有一定特征,但必须结合临床资料排除常见纵隔肿瘤后,方可提示本病的诊断,最终诊断尚需病理证实。
