Tumor-Induced Hypoglycemia: An Unusual Case Report and Review of Literature

Objective To describe a rare case of pheochromocytoma presenting with hypoglycemia. Methods We describe a rare case of pheochromocytoma presenting with a hypoglycemic seizure. Our article includes our differentials, work up, and management. Results Our patient had non–islet-cell tumor hypoglycemia that was non-insulin mediated, as noted by low insulin levels. His hypoglycemia was likely multifactorial and mediated by different mechanisms. We describe the rare case and review the causes of tumor-induced hypoglycemia. Conclusion Pheochromocytomas can rarely present with hypoglycemia and are associated with a poor prognosis.
