We report a 50-year-old man with severe primary hyperparathyroidism, very high parathyroid hormone levels, markedly elevated alkaline phosphatase and extensive skeletal disease, including a brown tumor with pathological fracture. Following parathyroidectomy, he developed persistent postoperative hypocalcemia with biochemical features suggestive of both transient postoperative hypoparathyroidism and hungry bone physiology. Despite high-dose calcium, calcitriol, and electrolyte replacement, hypocalcemia persisted, requiring intensive care unit admission and prolonged intravenous supplementation. Teriparatide was initiated on postoperative day 11 at a dose of 20\u2005\u00b5g twice daily, subsequently reduced to 20\u2005\u00b5g once daily. Thereafter, calcium levels progressively normalized, allowing discontinuation of intravenous supplementation and early hospital discharge. A short course was associated with sustained calcium\u2013phosphate stabilization without recurrence of hypocalcemia during follow-up. This case highlights the potential role of short-term teriparatide as rescue therapy in selected patients with persistent postoperative hypocalcemia and hungry bone features.<\/jats:p>","DOI":"10.1093\/ejendo\/lvag150","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T11:46:16Z","timestamp":1786535176000},"page":"K5-K11","source":"Crossref","is-referenced-by-count":1,"title":["Transient
