The detection rate of thyroid incidentalomas is increasing; in fact, as many as 2.3% of patients undergoing FDG PET-CT for other indications have been found to have thyroid incidentalomas. The risk of malignancy in these thyroid incidentalomas can be as high as 47%. The increased uptake and the focal uptake pattern of F-18 fluorodeoxyglucose (FDG) in the thyroid during positron emission tomography (PET)-computed tomography (CT), and the calcification of the thyroid incidentaloma, are associated with even higher risk of malignancy. We report a case of a lady undergoing FDG PET-CT for breast cancer staging but noted to have a calcified thyroid incidentaloma, which was proven to be follicular thyroid carcinoma.
甲状腺偶发瘤的检出率正在上升；事实上，在因其他指征接受氟代脱氧葡萄糖（FDG）正电子发射断层扫描（PET）-计算机断层扫描（CT）的患者中，多达2.3%被发现患有甲状腺偶发瘤。这些甲状腺偶发瘤的恶性风险可能高达47%。在正电子发射断层扫描（PET）-计算机断层扫描（CT）期间，甲状腺中F-18氟代脱氧葡萄糖（FDG）摄取增加和局灶性摄取模式，以及甲状腺偶发瘤的钙化，都与更高的恶性风险相关。我们报告一例因乳腺癌分期接受FDG PET-CT检查的女性病例，该患者被发现有钙化的甲状腺偶发瘤，经证实为滤泡状甲状腺癌。
