Fatal Generalized Metastatic Calcifications.

Metastatic calcifications are a rare but potentially fatal complication of primary hyperparathyroidism (PHPT). In this case, a 76-year-old man with a previously asymptomatic PHPT developed a hypercalcemic crisis with severe pancreatitis following elective urologic surgery. Despite initial treatment focused on pancreatitis and subsequent organ failure, hypercalcemia persisted, leading to rapid progressive metastatic calcifications in multiple organs. Parathyroidectomy during ongoing pancreatitis successfully reduced calcium levels but not the calcifications. After 4 months of complications and persistent pain, the patient declined further treatment and ultimately succumbed to the disease. The current literature primarily reports single-organ metastatic calcifications due to PHPT. This case represents the only lethal case of systemic metastatic calcifications in the current century. Physicians should be aware of the potential deterioration of hypercalcemia following elective surgery, particularly in the context of renal impairment. Rapid correction of calcium levels may prevent severe complications such as fatal metastatic calcifications. [ABSTRACT FROM AUTHOR]
