Hyperparathyroidism during pregnancy. Is it a diagnostic and therapeutic challenge

Background Primary hyperparathyroidism (PHPT) is characterized by an increase in parathyroid hormone (PTH) and hypercalcemia, which, when present during pregnancy, increases both maternal and fetal morbidity and mortality. Objective Emphasize the importance of surgical intervention in primary hyperparathyroidism during pregnancy. Clinical case A 27-year-old female with a pregnancy of 27.2 weeks of gestation, with a diagnosis of symptomatic primary hyperparathyroidism secondary to parathyroid adenoma, a history of nephrolithiasis and severe acute pancreatitis, surgery was decided upon finding intrathyroid right parathyroid adenoma, post-surgical course with adequate evolution and remission of hyperparathyroidism. Conclusions Parathyroidectomy in primary hyperparathyroidism during pregnancy is safe.
