A 46-year-old female patient with an euthyroid multinodular goiter underwent fine needle aspiration biopsy because ultrasound examination indicated a thyroid malignancy. In the postoperative evaluation of thyroidectomy material, a papillary thyroid carcinoma was detected in the right thyroid lobe with a maximum 2.2 cm diameter (T2N0Mx). The patient received radioiodine ablation treatment with 3700 MBq (100 mCi) iodine-131. Six months after RAT, diagnostic whole-body scintigraphy was performed with 185 MBq (5 mCi) I-131. Serum-stimulated Tg levels were 3.47 ng/mL, and I-131 scintigraphy results were normal. Neck ultrasound and computed tomography of the thorax were performed to search possible recurrent disease. There was no cervical lymph node or lung metastases.
