Eclampsia as the First Manifestation of Primary Hyperparathyroidism: a Case Report

Background: This study aimed to explore the diagnosis and treatment strategies of eclampsia during pregnancy and postpartum acute pancreatitis caused by primary hyperparathyroidism. Methods: This study reported a 26-year-old patient who had maternal eclampsia as her first symptom and was ad-mitted to the hospital. The pregnancy was terminated by cesarean section immediately. Postpartum life -threaten-ing complications, such as severe hypercalcemia and acute pancreatitis, occurred afterward. Following completion of the relevant examination, primary hyperparathyroidism was initially considered to be the cause. Symptomatic treatment is ongoing and will be improved, and the patient will be admitted again for parathyroidectomy. Results: The patient gave birth to a premature neonate via cesarean section. The postpartum diagnosis was prima-ry hyperparathyroidism, for which post-surgical pathology showed a parathyroid adenoma. Conclusions: The clinical manifestations of pregnancy with primary hyperparathyroidism are atypical but may cause serious maternal and fetal complications. Early diagnosis and appropriate treatment can prevent serious prenatal and postnatal complications and foster better pregnancy outcomes.
