title: Incidental Detection of Oxyphilic Papillary Thyroid Carcinoma by 18F-Fluorocholine PET/CT.
abstract: A 70-year-old man with prostate cancer and increased prostate-specific antigen level of 55 ng/mL underwent staging F-fluorocholine PET/CT, which demonstrated the primary prostate tumor and a focal area corresponding to a 2-cm hypodense nodule in the left thyroid lobe. Fine-needle aspiration and subsequent total thyroidectomy with central lymph node dissection showed an oxyphilic papillary thyroid carcinoma and a medullary microcarcinoma. Oxyphilic tumors represent a significant proportion of the few case reports of incidental focal thyroid fluorocholine thyroid uptake.
