[Abstract]
We report the case of a 62-year-old woman with nausea, vomiting, abdominal pain, polyuria, and polydipsia presenting to the emergency room and found to have new-onset diabetes with diabetic ketoacidosis (DKA). Incidentally discovered bilateral adrenal masses found during evaluation for possible abdominal abscess prompted further investigation, and pheochromocytoma was confirmed through biochemical analysis. She was treated with adrenalectomy, resulting in resolution of diabetes. This case demonstrates a unique presentation of pheochromocytoma with DKA.
