The diagnosis of hypoglycemia is confirmed by Whipple's triad: symptoms of hypoglycemia, low plasma glucose concentrations, and disappearance of symptoms after glucose administration. The case of a 26-year-old woman is presented. She consulted our Service in July 2013 due to intermittent episodes that had begun in October of the preceding year, characterized by blurred vision, slurred speech, and behavioral changes, unrelated to food ingestion. They increased in frequency, and were associated eventually with loss of consciousness and loss of sphincters control, requiring medical care. Occasionally, low capillary glucose levels were recorded, and there was improvement in symptoms with i.v. glucose administration ev. During a fasting test she had symptomatic hypoglycemia with serum glucose of 48 mg/dl, serum insulin 21.1 μU/ml, and serum C-peptide 2.257 ng/ml. Abdominal ultrasound identified a rounded image in the union of the body and tail of the páncreas; this was confirmed by MRI. The lesion was surgically enucleated, and the pathology report confirmed its neuroendocrine origin. Source
