Acute Pancreatitis in a patient with hypercalcemia due to tertiary hyperparathyroidism

Abstract

Hypercalcemia represents an independent risk factor of acute pancreatitis and can result from hyperfunctioning parathyroid glands. Here, we report on a 35-year-old patient who was admitted to our hospital with abdominal pain six weeks after kidney transplantation. Based on laboratory tests and ultrasound imaging, acute pancreatitis with hypercalcemia due to tertiary hyperparathyroidism was diagnosed. Subsequently, the patient was treated by parathyroidectomy with autologous tissue transplantation. This constellation points to acute pancreatitis as a very rare and severe complication of patients developing tertiary hyperparathyroidism-related hypercalcemia from secondary hyperparathyroidism after kidney transplantation.
