Pheochromocytoma is a rare catecholamine-secreting tumour that arises from chromaffin cells in the adrenal medulla or extra-adrenal sympathetic ganglia. It classically presents with paroxysmal headaches, hypertension, palpitations and sweating related to catecholamine excess. Diabetes is reported to be present in approximately one-third of patients with pheochromocytoma; however, diabetic ketoacidosis is an extremely rare complication. We present a case of an African-American male aged 30 years who initially presented with diabetic ketoacidosis and hypertensive urgency whose blood pressure and glycaemic control improved remarkably following tumour excision. We will discuss this unusual presentation of pheochromocytoma along with a management approach for such adrenal incidentalomas.
