A 53-year-old man underwent both 18 F-FDG and 68 Ga-PSMA PET/CT to evaluate a mass in the left upper abdomen. The scans demonstrated intense uptake of both 18 F-FDG and 68 Ga-PSMA in the mass. However, a nodule in the left lobe of the liver showed increased uptake of 68 Ga-PSMA, which was not FDG avid. Histopathological examination after surgical resection of the mass confirmed the diagnosis of pancreatic neuroendocrine tumor (G2). Subsequently, 68 Ga-DOTATATE PET/CT demonstrated intense radioactivity of the nodule in the left lobe of the liver consistent with hepatic metastasis from neuroendocrine tumor.
一位 53 岁男性因左上腹肿块而行 18 F-FDG 和 68 Ga-PSMA PET/CT 检查。扫描显示肿块对 18 F-FDG 和 68 Ga-PSMA 均有强烈摄取。然而，左肝叶的一个结节显示出对 68 Ga-PSMA 的摄取增加，而对 FDG 不摄取。肿块切除术后的组织病理学检查证实了胰腺神经内分泌瘤（G2）的诊断。随后，68 Ga-DOTATATE PET/CT 显示左肝叶结节的放射性活性明显增强，符合神经内分泌瘤的肝转移。
