Abstract

PSMA-targeted PET/CT can be used for diagnosis and staging of clear cell renal cell carcinoma. A 68-year-old woman with suspected hepatic metastases from clear cell renal cell carcinoma underwent PET/CT with 68Ga-PSMA, which showed a focus of moderately increased tracer uptake in the right thyroid lobe. Sonography displayed a correlating hypoechogenic, ill-defined node (TIRADS 5). Right hemithyroidectomy was performed in the assumption of a solitary metastasis of renal cell carcinoma. Histologic examination revealed subacute granulomatous thyroiditis (De Quervain thyroiditis) without evidence of malignancy.

摘要

PSMA 靶向 PET/CT 可用于透明细胞肾细胞癌的诊断和分期。一位 68 岁女性疑似患有透明细胞肾细胞癌肝转移，进行了 68Ga-PSMA PET/CT，结果显示右甲状腺叶有一处中度放射性摄取增加的病灶。超声显示相应的低回声、边界不清的结节（TIRADS 5）。考虑为肾癌单发转移，行右甲状腺半切除术。组织学检查显示亚急性肉芽肿性甲状腺炎（De Quervain 甲状腺炎），无恶性证据。
