Background: Graves disease is the most common cause of hyperthyroidism in children. The frequency of the disease increases with age, peaking during adolescence.Thyroid storm is a rare but critical, ilness that can lead to multiorgan failure and carries a high death rate. Antithyroid drugs are usually recommended as the initial treatment and are generally well tolerated. Although current treatment options include radioactive iodine, but long term complications of thyroid irradiation is not well known. Near total or total thyroidectomy is an acceptable form of therapy too. Reactions to antithyroid drug medication makes the decision harder for choosing the suitable therapeutic option.

Case: A 10 years old girl administrated to our outpatient clinic with palpitation, tremor, anxiety, sleepless, weight loss and fatigue. She was administered to another center with thyroid storm and diagnosed as Graves disease. The antithyroid drug therapy (methimazole and propranalol) was initiated to patient but she had angioneurotic edema. Following either propranalol or methimazole administration alone resulted with angioneurotic edema. In this situation the patient was reffered to our clinic for radioactive iodine ablation therapy. Physical examination and laboratory findings were given at Table 1. Under this circumstances thyroid ablation with 131I seems to be a good solution but her iodine turnover was very high (4th h: 62.4%; 24th h 54.6%) and so the response will be poor and needs to be administered with higher recurent doses. Plasmapheresis could be another option in preparation for total thyroidectomy but it was risky.High dose oral glucucorticoid and antihistaminic therapy combined with propranolol was administered before surgery. Her thyroid hormone levels were decreased %70 in a week and total thyroidectomy was performed without any complication Postoperation period LT4 therapy was initiated.

Conclusion: In conclusion inorder to underline allergical reactions of antithyroid therapy, we wanted to remined oral steroid therapy benefits combined with surgery.
