Ga-labeled prostate-specific membrane antigen (PSMA) ligand PET/CT is a rapidly evolving imaging modality for prostate cancer. However, with the widespread use of Ga-PSMA PET/CT, various reports of nonprostatic uptake of Ga-PSMA in both benign and malignant lesions have also appeared. We report a recently diagnosed case of prostate cancer demonstrating diffuse Ga-PSMA expression in both the lobes of thyroid gland, which on further clinical and biochemical investigations was established as hypothyroidism.
Ga 标记的前列腺特异性膜抗原 (PSMA) 配体 PET/CT 是一种用于前列腺癌的快速发展的成像方式。然而，随着 Ga-PSMA PET/CT 的广泛应用，在良性和恶性病变中也出现了各种 Ga-PSMA 非前列腺摄取的报告。我们报告了一例最近诊断的前列腺癌病例，该病例在甲状腺的两个叶中均表现出弥漫性 Ga-PSMA 表达，进一步的临床和生化研究确定为甲状腺功能减退症。
