The authors present the case of a 78-year-old female patient who was admitted on account of acute pancreatitis complicated by acute myocardial infarction. The authors detected in the pati- ent s serum repeatedly high calcium levels and high levels of intact parathormone. Scintigraphic examination revealed marked foci in the middle of the neck at the level of the inferior pole of the thyroid gland. These examinations confirmed the diagnosis of primary hyperparathyroidism. In view of the patient s serious condition, conservative treatment of hypercalcaemia and acute pancreatitis and myocardial infarction was started. The patient was released into domiciliary care after 40days in hospital in a state of cardiopulmonary compensation , with cystic transforma- tion of the pancreas and without signs of acute pancreatitis.
