Graves' thyrotoxicosis soon after hemithyroidectomy for low-risk papillary thyroid carcinoma.

Hyperthyroidism is a medical problem that is commonly encountered by emergency physicians, internists and endocrinologists. The development of hyperthyroidism in the postoperative setting of hemithyroidectomy is quite rare. Reported causes include destructive thyroiditis and inappropriate thyroid hormone replacement. Here we report a case of Graves' disease causing thyrotoxicosis soon after surgery in a woman who underwent hemithyroidectomy for low-risk papillary thyroid carcinoma.
