Figure 1 Findings from computed tomography. A: Unenhanced computed tomography (CT) image shows a slight low attenuating lesion (arrow) in pancreatic uncinated process and head and dilatation of gallbladder; B: Contrast-enhanced arterial phase CT image shows minimal enhancing low attenuating lesion (long arrow) surrounding a few tubular low cystic attenuating structures (short arrow), and homogenous highly enhancing normal pancreas (arrowhead); C: Contrast-enhanced portal venous phase CT image shows delayed enhancing lesion (long arrow) containing a few tubular cystic structures (short arrow).
