Objective: Amiodarone-induced thyrotoxicosis (AIT) is usually classified into 2 types (type 1, in which a high iodine content triggers the autonomous production of thyroid hormone; and type 2, in which destructive thyroiditis causes the release of preformed thyroid hormone). A mixed form of AIT has also been also described. AIT is a difficult management problem that sometimes requires ablative thyroid therapy. The use of radioactive iodine (RAI) therapy in patients with type 1...

Introduction: Radioiodine can be used for the ablation/treatment and imaging of thyroid cancer. However, radioiodine uptake is not specific for thyroid tissue. Iodine-131 can show physiologic accumulation in several organs as breast, thymus, liver and gastrointestinal tract, or in benign conditions, such as cysts and inflammation, or in a variety of benign and malignant non-thyroidal tumors, which could be mistaken for thyroid cancer or cancer metastasis. Here we aimed to eval...
