Abstract
Hypercalcemic hyperparathyroid crisis is an infrequent but life threatening complication of main hyperparathyroidism. It is an infrequent manifestation for primary hyperparathyroidism by reason of parathyroid adenoma presenting with parathyroid storm. Acute hypercalcemic hyperparathyroid crisis is a rapidly developing syndrome characterized by severe hypercalcemia associated with life threatening disturbances in cardiac, renal, cerebral functions. This state should be doubted in acutely ill cases with gastrointestinal appearances, profound dehydration, changed mental state, urinary signs or cardiac arrhythmias. We offer this patients to give emphasis to the significance management of an acute hypercalcemic syndrome and early diagnosis as a result of primary hyperparathyroidism as a cause of an undefined adenoma of the parathyroid gland. We present this patients to give emphasis on early and rigorous treatment of hypercalcemic crisis as a result of parathyroid storm otherwise it could be fatal.
