Pancreatic Insulinoma Presenting with Postprandial Hypoglicemias

We report the case of an obese 58 years old patient evaluated for hypoglycemia. The response to a prolonged fasting test was normal, but symptomatic hypoglycemia ensued after mixed meals and with oral glucose loading. A magnetic resonance scan of the abdomen revealed a pancreatic tail tumor, histologically diagnosed as benign insulinoma after successful laparotomy. "Glucose-responsive" insulinomas, although rare, have been previously described in the literature. Therefore, the diagnosis of insulinoma should also be considered in patients that exhibit postprandial rather than fasting hypoglycemia.
