The widespread use of highly sensitive imagingtechniques has led to the serendipitous identifi-cation of subclinical tumors in some organs [1].Pancreatic incidentaloma (PI) has been definedas a mass that is incidentally discovered duringan image study for symptoms other than the onesof the mass itself or the organ affected. The term‘‘pancreatic incidentaloma’’ was first describedby Ho and Kostiuk [2, 3]. The incidence of PIvaries among different studies. In a series of 333asymptomatic potential kidney donors, twocases of PI (0.6%) were found [4]. In a recentreport analyzing the Japanese experience of PETfor cancer screening in 39,785 asymptomaticsubjects, six cases of unsuspected pancreatic can-cer (0.01%) were discovered [5]. Some studieshave suggested that the incidence is rising [6].
