Recurrent Pancreatic Pseudocyst Secondary to Hypercalcaemia with Underlying Parathyroid Adenoma

Abstract

We report a case of recurrent pancreatic pseudocyst secondary to primary hyperparathyroidism (PHPT). The patient presented with a large left sided pancreatic pseudocyst (PP) complicated with pancreatic abscess requiring long term antibiotic therapy and imageguided drainage. The patient had persistent hypercalcaemia which after several investigations led us to the diagnosis of PHPT. We performed an elective parathyroidectomy after the expectant management for the pancreatitis complicated with pancreatic pseudocyst. Although hypercalcaemia is the 4th common cause of pancreatitis, its exact association between those primary hyperparathyroidism and pancreatitis is unclear.
