A 23-year-old female patient, suffering from frequent hypoglycemic attacks, was referred to our institution for suspected hyper-functioning pancreatic endocrine tumor. Clinical and laboratory tests suggested endogenous hyper-insulinemic hypoglycemia. Because previous imaging was unable to localize the tumor, Volume Perfusion CT (VPCT) of the pancreas was ordered by the clinician for insulinoma localization.
