Case report: From metabolic instability to remission: a case of pheochromocytoma presenting as atypical diabetes

This case demonstrates that pheochromocytoma can induce a severe, reversible form of diabetes characterized by profound metabolic instability and marked glycemic variability. It highlights the necessity of including pheochromocytoma in the differential diagnosis of patients with atypical, labile diabetes, especially when paroxysmal symptoms are present. Early surgical intervention can reverse these metabolic derangements, often leading to diabetes remission.
