{Reference Type}: Case Reports {Title}: Bisphosphonate-Induced Orbital Cellulitis in a Patient With Suspected Parathyroid Carcinoma: A Case Report. {Author}: McKenna T;McKenna DE;Fernandes V;Korda M;Bradley U; {Journal}: Cureus {Volume}: 16 {Issue}: 7 {Year}: 2024 Jul 暂无{DOI}: 10.7759/cureus.63577 {Abstract}: Bisphosphonates are widely used for a number of metabolic bone conditions. Orbital inflammation is a very rare side effect of bisphosphonate therapy that can risk permanent visual loss. We describe the complex case and successful treatment of a 79-year-old man who developed orbital cellulitis following the use of intravenous pamidronate disodium for severe hypercalcaemia. The challenges regarding the diagnosis of parathyroid carcinoma are also discussed.
