FDG PET/CT and PET/MRI were performed to evaluate a cystic lesion in the body of the pancreas in a 65-year-old man. Neither studies showed abnormally increased activity in the cystic lesion in the body of the pancreas. However, both studies revealed abnormal activity in the neck of the pancreas, which did not show anatomical abnormality and was not suspected prior to the PET imaging. Pathological examination demonstrated that the lesion in the body of the pancreas was a benign duct dilation, whereas the abnormal FDG activity in the neck of the pancreas was due to pancreatic adenocarcinoma.
