Background: Hypercalcemia during pregnancy leads to multiple maternal and fetal complications. To date, fewer than 30 cases of primary hyperparathyroidism (PHPT)-induced pancreatitis have been diagnosed during pregnancy. Most cases have been caused by a parathyroid adenoma. In the present report, the author described the first case of PHPT due to parathyroid hyperplasia presented with recurrent, acute pancreatitis during pregnancy.
Case Report: A 38-year-old female, with a history of acute pancreatitis during her first pregnancy, presented with severe epigastric pain, nausea, and vomiting for three days at 24 weeks of gestation. Parathyroid-dependent, hypercalcemia-induced recurrence of pancreatitis was diagnosed based on the clinical presentation and laboratory investigations. An ultrasound on her neck revealed a possible parathyroid adenoma located on the inferior pole of the left thyroid gland. She underwent an uneventful left-lower parathyroidectomy. The pathological examination revealed parathyroid hyperplasia. Her serum calcium and parathyroid hormone levels returned to normal after surgery. She delivered a healthy male newborn at gestational age 38 weeks without any complications.
Conclusion: PHPT-induced acute pancreatitis during pregnancy is rare. Hypercalcemia, involving both total and ionized calcium, should be investigated in pregnant women who present with acute pancreatitis. Early diagnosis and appropriate management can significantly improve the maternal, fetal, and pregnancy outcomes.
