A patient of differentiated follicular thyroid carcinoma with unusual sites of metastases is illustrated with I and F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) imaging findings. The described case harbored extremely rare metastasis to the urinary bladder with multi-organ metastatic disease (including unusual sites of right bronchus and hepatic metastases). There was inter-lesional heterogeneity among the metastatic lesions with regard to the I and FDG uptake in the aforementioned lesions. The detection of such heterogeneity has important implications for patient management in metastatic differentiated thyroid carcinoma.
本文通过碘-131和氟-18氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（F-FDG PET/CT）成像结果展示了一例具有不寻常转移部位的分化型滤泡状甲状腺癌患者。所描述的病例发生了极为罕见的膀胱转移以及多器官转移疾病（包括右支气管和肝脏等不寻常部位的转移）。在上述转移病灶中，碘-131和氟代脱氧葡萄糖摄取方面存在病灶间异质性。检测到这种异质性对转移性分化型甲状腺癌患者的管理具有重要意义。
