A Rare Triad: Hypercalcemia-Induced Necrotizing Pancreatitis Presenting as Severe Diabetic Ketoacidosis

Abstract

Primary hyperparathyroidism (PHPT) typically occurs in persons above 45 years, with a female predominance. PHPT induces a state of hypercalcemia, but acute pancreatitis is a rare sequelae of this hypercalcemia. We report a case of a 31-year-old man with no known medical history who presented in diabetic ketoacidosis with electrolyte abnormalities. His clinical course progressed to multi-organ dysfunction despite correction of metabolic derangements. Further workup led to the discovery of the uncommon triad by which previously undiagnosed PHPT precipitated severe diabetic ketoacidosis.
