It is known to produce thyroid abnormalities ranging from abnormal thyroid function testing to overt hypothyroidism or hyperthyroidism. These adverse effects may occur in patients with or without preexisting thyroid disease. Amiodarone-induced thyrotoxicosis (AIT) is a clinically recognized condition commonly due to iodine-induced excessive synthesis of thyroid, also known as type 1 AIT. In rare instances, AIT is caused by amiodarone-induced inflammation of thyroid tissue, resulting in release of preformed thyroid hormones and a hyperthyroid state, known as type 2 AIT. Distinguishing between the two states is important, as both conditions have different treatment implications; however, a mixed presentation is not uncommon, posing diagnostic and treatment challenges. We describe a case of a patient with amiodarone-induced type 2 hyperthyroidism and review the current literature on the best practices for diagnostic and treatment approaches.<\/jats:p>","DOI":"10.1155\/2014\/231651","type":"journal-article","created":{"date-parts":[[2014,11,12]],"date-time":"2014-11-12T21:01:08Z","timestamp":1415826068000},"page":"1-6","source":"Crossref","is-referenced-by-count":7,"title":["Amiodarone-Induced Thyrotoxic Thyroiditis: A Diagnostic and Therapeutic Challenge"],"prefix":"10.1155","volume":"2014","author":[{"given":"Umang","family":"Barvalia","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Marshfield Clinic, 1000 N.
