A 51-year-old man with a history of surgical removal of sigmoid colon cancer underwent F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) to search for distant metastases and/or local recurrence because the carcinoembryonic antigen level was elevated. F-18 FDG PET images showed increased focal FDG uptake in the left lobe of the thyroid. Computed tomography images showed thyroid tumor in the left lobe as well as F-18 FDG PET images. Thereafter he underwent thyroidectomy and the resected specimen was histopathlogically shown to have thyroid metastasis from colon cancer. F-18 FDG PET was useful to detect thyroid metastasis from colon cancer as well as the most frequently seen metastatic sites such as liver, lungs, and lymph nodes.
一名有乙状结肠癌手术切除史的51岁男性，因癌胚抗原水平升高，接受了F-18氟脱氧葡萄糖（FDG）正电子发射断层扫描（PET）以寻找远处转移和/或局部复发。F-18 FDG PET图像显示甲状腺左叶局灶性FDG摄取增加。计算机断层扫描图像以及F-18 FDG PET图像均显示甲状腺左叶有肿瘤。此后，他接受了甲状腺切除术，切除标本的组织病理学检查显示为结肠癌甲状腺转移。F-18 FDG PET对于检测结肠癌的甲状腺转移以及最常见的转移部位如肝脏、肺和淋巴结很有用。
