Hyperparathyroid crisis (parathyroid storm, parathyroid intoxication) is a rare syndrome of severe hypercalcemia in a patient with primary hyperparathyroidism.
Patients may have parathyroid adenomas or parathyroid carcinomas.
The clinical syndrome may be precipitated by illness, drugs, childbirth or trauma.
(1) primary hyperparathyroidism with elevated parathyroid hormone (PTH).
(2) profound elevation of serum calcium (> 14 mg/dL)
(3) clinical signs and symptoms of hypercalcemia:
(3a) mental status changes
(3b) nausea and vomiting
