Severe Acute Pancreatitis as an Index Clinical Manifestation of Parathyroid Adenoma.

Hypercalcemia due to primary or secondary hyperparathyroidism is a rare and obscure cause of acute pancreatitis. Although a rare occurrence to begin with, hyperparathyroidism commonly manifests with symptoms of hypercalcemia. Thus, it would reason that a patient might develop pancreatitis by way of hypercalcemia due to primary or secondary hyperparathyroidism. We present a case of an 88-year-old female with acute pancreatitis and only after an extensive work-up, was it determined that her severe acute pancreatitis resulted from primary hyperparathyroidism caused by a left parathyroid adenoma.
