A pregnant woman with primary hyperparathyroidism: a case report

Abstract

Primary hyperparathyroidism is diagnosed with an increase of calcium levels and a decrease in phosphoruslevels. Primary hyperparathyroidism is a rare condition in pregnancy. Calcium levels tend to be low in pregnantwomen, and high levels of calcium can point a primary hyperparathyroidism. Here, we report an original caseof a pregnant woman with primary hyperparathyroidism who was fully healed after the surgery. A 30-year-oldpregnant women (10thgestational week), admitted to the endocrinology department for management ofthyrotoxicosis, when high calcium levels (11.8 mg/dL) were found in the laboratory tests. The parathyroidhormone level was 135 pg/ml. Ultrasound imaging revealed a parathyroid adenoma (12x7x27mm). She hadmaintained high calcium levels despite the medical treatment, for this reason, she had surgery in the secondtrimester. Our case was diagnosed early due to early recognition of calcium elevation. The mother and thefoetus had not any complication. Pregnant women tend to have low calcium levels hence if a hypercalcemiasituation appears in pregnant women; primary hyperparathroidism has to be suspected.
