Abstract

Postpartum hypoglycemia in non-diabetic women is a rare condition. We report the case of a 34-year-old woman who experienced neuroglycopenia 2 days after delivery. Corresponding to severe hypoglycemia, we found inappropriately elevated insulin and C-peptide levels. Following magnetic resonance imaging a lesion of 10x8 mm was detected in the head of the pancreas. An ultrasound-guided fine needle aspiration of the mass confirmed the diagnostic suspicion of a pancreatic neuroendocrine tumor. Complete surgical enucleation of the insulinoma resulted in immediate and permanent resolution of the hypoglycemia. The postoperative course was uneventful. Histopathological and immunohistochemical analyses were consistent with insulinoma. The diagnostic approach to postpartum hypoglycemia represents a challenge for multidisciplinary teamwork.
