Computerized axial tomography (CT scan) of the abdomen is a sensitive method for examining the pancreas. Its sensitivity, however, may lead to the discovery of small mass lesions which do not represent neoplastic or inflammatory lesions. We describe our experience with 21 patients in whom mass lesions seen by CT scan were proven by endoscopic retrograde pancreatography (ERCP) to represent anomalies of the pancreatic duct. We call such lesions "pseudomasses." Our findings support the need for opacification of the pancreatic duct system to rule out lesions arising from the duct whenever lesions of the pancreas are suspected on CT scan.
腹部计算机断层扫描（CT扫描）是检查胰腺的一种敏感方法。然而，其敏感性可能会导致发现一些并非肿瘤性或炎性病变的小肿块病变。我们描述了21例患者的情况，这些患者经CT扫描发现的肿块病变经内镜逆行胰胆管造影（ERCP）证实为胰管异常。我们将这类病变称为“假肿块”。我们的研究结果支持，当CT扫描怀疑胰腺有病变时，需要对胰管系统进行造影，以排除源于胰管的病变。
