胰腺炎误诊胰腺癌CT及MRI征像分析

目的 从误诊为胰腺癌病例中寻找胰腺炎的影像特征。 方法 回顾性分析2001-2010年第二军医大学附属长征医院22例误诊为胰腺癌的胰腺炎CT、MRI影像学资料。 结果 误为局限性胰腺癌的胰腺炎有5种表现：胰腺局限性增大，胰腺内坏死、假性囊肿，胰腺不均匀脂肪沉积，继发于胰腺分裂的胰管潴留性扩张或胰管积血。误为弥漫性胰腺癌的胰腺炎有3种表现：胰腺弥漫肿大，胰腺广泛乏血供病变，胰腺周围没有渗出。误为胰腺外转移的胰腺炎有2种表现：胰旁假性囊肿、炎性结节误认为转移淋巴结，局部静脉血栓、动脉狭窄误认为血管侵犯。 结论 对表现不典型的胰腺癌均应想到胰腺炎或合并胰腺炎可能，应完整了解病史，仔细分析影像学特点和变化规律，密切随访。
