Hypercalcemia induced pancreatitis as a rare presentation of primary hyperparathyroidism.

Acute pancreatitis (AP) is an inflammatory process of the pancreas. It is a relatively common cause of acute upper abdominal pain and is potentially associated with high morbidity and mortality. Underlying hypercalcemia as a cause of AP is very rare. We present a case of a hypercalcemia-induced acute pancreatitis with an underlying parathyroid adenoma in an 81-year-old woman with no previous symptoms of hypercalcemia. The parathyroid adenoma was semi-urgently surgically resected with normalization of calcium-levels. This case report summarizes the causes of acute pancreatitis and hypercalcemia and its management.
