More than 80% of the patients are asymptomatic and are usually diagnosed with incidentally detected high serum calcium levels. Concominant elevated levels of serum calcium (Ca++) and parathyroid hormone (PTH) is important in definitive diagnosis. Parathyroidectomy is the definitive treatment for primary hyperparathyroidism. Here, we report a patient with high serum calcium levels related to parathyroid adenoma and treated in intensive care unit (ICU). 54 years old female patient who is under treatment of osteoporosis had the symptoms of muscle weakness, fatigue, dizziness, vomiting, dehydration, polyuria and depression. High serum Ca+ and PTH levels were returned to normal after surgical excision.turinfo:eu-repo/semantics/closedAccessPrimary hyperparathyroidismparathyroid adenomasurgeryArticle1131271300003751556000082-s2.0-849443891851305-9327
