case_images: Her past surgical history showed that she underwent total thyroidectomy and lymph node dissection for follicular variant papillary thyroid carcinoma pT2N1cM0 (Figure 1) in March 2002, followed by radioactive iodine (RAI) ablation 150 mCi in May 2002, and RAI ablation 150 mCi in July 2003 for raised serum thyroglobulin levels (39.3 ng/mL).
