A 49-year-old pancreatic cancer patient. A-C: CECT images at the arterial phase, pancreatic parenchymal phase, and delayed phase. A tiny, round, low density, 9 mm lesion was found at the posterior right liver lobe (arrow). This lesion was diagnosed as a hepatic cyst by CECT imaging because no enhancement was found in the lesion; D: A PET/CECT fusion image showed increased FDG uptake at the lesion with an SUVmax of 5.2. This lesion was diagnosed as liver metastasis from pancreatic cancer with PET/CECT fusion images, which was confirmed by biopsy; E: PET image for the entire body. A high metabolic mass was found at the pancreatic head (triangle). PET/CT: Positron emission tomography/computed tomography; CECT: Contrast-enhanced CT; FDG: Fluorodeoxyglucose.
