title: Pancreatic pseudocyst resolution after parathyroidectomy for hyperparathyroidism.
abstract: Hyperparathyroidism is a rare cause of pancreatic inflammatory disease. Appropriate treatment of coexistent hyperparathyroidism and pancreatitis, especially when complicated by pseudocyst formation, is unsettled. We describe two patients with primary hyperparathyroidism who developed pancreatitis associated with multiple pseudocysts. The largest cyst in each patient was 9 and 5 cm, respectively. After correction of hyperparathyroidism and normalization of serum calcium levels by removal of a parathyroid adenoma, the pseudocysts resolved in both patients, as documented with computed tomography. We conclude that uncomplicated pancreatic pseudocysts in patients with primary hyperparathyroidism can be treated expectantly. Surgical correction of hyperparathyroidism and normalization of serum calcium levels should precede pancreatic intervention when possible, since pseudocyst resolution is likely and the risks of postoperative hypercalcemia are avoided.
