ECE2017 Eposter Presentations: Thyroid Thyroid (non-cancer) (260 abstracts)
Department of Nuclear Medicine, Salah Azaiez Institute, Tunis, Tunisia.
Introduction: Gravess disease is the most common cause of hyperthyroidism. There are three current therapeutic options: anti-thyroid medication, surgery, and radioactive iodine (I 131). There are few data in the literature regarding the effects of radioiodine therapy.
Case report: We describe a 47-year-old patient who had Graves disease resistant to anti thyroid medication. Radioactive iodine was indicated. The patient was reluctant because she had a history of anaphylactic reaction to computed tomography (CT) contrast agent. We explicated to the patient that the implication of iodine has never been demonstrated during allergic hypersensitivity reactions due to iodinated drugs. She successfully underwent treatment with 12 mCi (444 MBq) radioactive iodine.
Conclusion: Asking a patient if he/she is allergic to iodine is a question that should be avoided because its significance is null. A diagnosis of drug allergy, essentially relying on clinical symptoms, biological tests and cutaneous tests, is required to take adequate preventive measures.
