Abstract

We report the case of a patient with hypoglycemic symptoms and weight gain.  Biochemical investigations revealed endogenous hyperinsulinemic hypoglycemia.  A CT scan and MRI of the abdomen were initially not successful in localizing a pancreatic mass.  However, an endoscopic ultrasound was able to demonstrate a pancreatic head mass.  Enucleation of the mass resulted in clinical and biochemical improvement.  This report also demonstrates the pattern of weight loss after surgery, showing an initial phase of gradual weight loss followed by a rapid loss of weight.  This pattern of weight loss after successful removal of an insulin-producing pancreatic neuroendocrine tumor is a novel addition to the existing knowledge we have about this condition.
