PEREYRA, Pilar de las Mercedes et al. Primary hyperparathyroidism in pregnancy: a case report highlighting uncommon complication. Medicina (B. Aires) [online]. 2024, vol.84, n.2, pp.342-346. ISSN 0025-7680.

Primary hyperparathyroidism (PHPT) is characterized by elevated levels of calcium and parathyroid hormone (PTH). However, the interpretation of diagnostic tests, such as serum calcium and PTH levels, is complex in pregnant women. The aim of this report is to present a case of PHTP in a pregnant adolescent, with a special emphasis on an uncommon complication, as well as diagnostic and treatment strategies.

A 17-year-old pregnant female presented with hyper emesis gravidarum and neurological symptoms, leading to the diagnosis of cerebral venous thrombosis. Further investigations revealed hypercalcemia and persistently elevated PTH levels, consistent with PHPT. After local ization studies, the patient underwent an emergency parathyroidectomy with a diagnosis of parathyroid ad enoma. During follow-up, intrauterine growth restric tion and severe preeclampsia developed, necessitating an emergency cesarean section. Both the mother and neonate had favorable outcomes.

PHPT is an infrequent condition in the pregnant population, and its diagnosis can be challenging due to the overlap of symptoms with normal physiological changes during pregnancy. The occurrence of uncom mon complications, such as thrombotic phenomena, highlights the need for a comprehensive approach to ensure early detection and management. In most cases, parathyroidectomy is the treatment of choice.
