Uncommon Presentation of Primary Hyperparathyroidism: A Case Report and Literature Review

IntroductIonPrimary hyperparathyroidism (PHPT) is an endocrine disorder characterized by increased serum calcium and parathyroid hormone (PTH) values.Clinical manifestations are variable from mild forms (renal colic, osteomuscular pain, asthenia) to more severe forms (venous thromboembolisms, pancreatitis, neurological alterations); their severity is proportional to calcium values.The diagnosis of PHPT is biochemical, based on the dosage of PTH, calcium, and phosphate.Localization tests are used to identify the affected gland(s) responsible for the disease.Surgical intervention is the only effective treatment: it consists of the removal of the affected gland(s) and then the monitoring of the PTH values and its return to the normal range after its removal. case descrIptIonA 77-year-old female patient arrived at the emergency room (ER) in December 2023 after being found on the ground at her place for an unspecified time.Her medical history included arterial hypertension and a paranoid disorder.Upon arrival at the ER, the patient was in fair general condition, hypothermic but without neurological compromise.
