A 64-year-old female patient, suffering from frequent hypoglycemic attacks, went to a local hospital for a checkup. Clinical and laboratory tests revealed endogenous hyper-insulinemic hypoglycemia. An insulinoma was suspected. A routine abdominal contrast CT was performed, however no tumor was seen. Subsequently, the patient was referred to our institution and a Dynamic CT, covering the liver and the entire pancreas, was performed. The CT data were then used to create different temporal phases and functional parameter maps.
