Bilateral Vocal Fold Paralysis Secondary to Intrathyroidal Calcifications Following Remote Administration of Radioactive Iodine Therapy for Graves Disease

摘要

Common causes of vocal fold paralysis (VFP) include traumaor iatrogenic injury, malignancy, and neurogenic conditions.1Other uncommon etiologies include a large intrathyroidal calcificationresulting from radioactive iodine ablation (RAI).2Unilateral VFP can result in hoarseness and dysphagia, whilebilateral VFP can result in respiratory distress due to narrowingof the airway at the glottis.
