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.

摘要

一位 70 岁男性，患有前列腺癌，前列腺特异性抗原水平升高至 55ng/mL，进行了 F-氟代胆碱 PET/CT 分期检查，结果显示原发性前列腺肿瘤和左甲状腺叶对应于 2cm 低密结节的局灶性区域。细针抽吸和随后的全甲状腺切除术及中央淋巴结清扫术显示为嗜酸细胞性甲状腺乳头状癌和髓样微癌。嗜酸细胞性肿瘤在少数偶然发现的甲状腺氟代胆碱摄取局灶性甲状腺摄取的病例报告中占很大比例。
