A 52-year-old woman was evaluated for the appearance of a neck lump and dysphonia. Neck ultrasonography showed a large cystic nodule in the right thyroid lobe, confirmed by fine-needle aspiration cytology. Thyroid function and calcitonin were normal. 18 F-FDG PET/TC showed moderate tracer uptake by the outer ring of the large hypodense formation. Right hemithyroidectomy was performed; since intraoperative histology showed an intracystic and invasive papillary thyroid carcinoma, a completion thyroidectomy was done. Definitive histopathology confirmed the intraoperative findings. 18 F-FDG PET/CT may be a useful imaging procedure in evaluating patients with cystic thyroid nodules whenever clinical/ultrasonographic features are suspicious for malignancy.
一位 52 岁女性因颈部肿块和声音嘶哑就诊。颈部超声显示右甲状腺叶有一个大的囊性结节，细针穿刺细胞学检查证实了这一点。甲状腺功能和降钙素正常。18 F-FDG PET/CT 显示大的低密度形成物的外环有中度示踪剂摄取。行右侧甲状腺叶切除术；由于术中组织学显示囊内和侵袭性甲状腺乳头状癌，因此进行了全甲状腺切除术。明确的组织病理学证实了术中发现。当临床/超声特征提示恶性肿瘤时，18 F-FDG PET/CT 可能是评估囊性甲状腺结节患者的一种有用的影像学检查方法。
