Life-threatening hypercalcemia associated with primary hyperparathyroidism during pregnancy: case report and review of literature.
OBJECTIVE
To report a case of life-threatening hypercalcemia attributable to primary hyperparathyroidism in a pregnant patient and discuss the management of severe hypercalcemia during pregnancy.


METHODS
We describe a 28-year-old pregnant woman who had life-threatening hypercalcemia (serum calcium level of 25.8 mg/dL). Primary hyperparathyroidism was diagnosed. The patient's management and the published medical literature on primary hyperparathyroidism during pregnancy are reviewed.


RESULTS
Our patient had the highest reported serum calcium level that we could find attributable to primary hyperparathyroidism during pregnancy. After initial stabilization, parathyroidectomy was successfully performed during pregnancy. To our knowledge, this is the first report in which this profound degree of hypercalcemia did not result in an adverse maternal or fetal outcome.


CONCLUSIONS
Although uncommon, primary hyperparathyroidism during pregnancy may be associated with severe maternal and perinatal complications. Life-threatening hypercalcemia due to primary hyperparathyroidism during pregnancy can be successfully managed surgically during pregnancy, with good maternal and fetal outcome.
