Abstract

We present 2 cases of metastatic castration-resistant prostate carcinoma with discordant lesions on dual-tracer PET/CT (⁶⁸Ga-PSMA-11 and ¹⁸F-FDG PET/CT), which on subsequent histopathologic evaluation revealed second primary malignancies of combined hepatocellular carcinoma and cholangiocarcinoma and poorly differentiated squamous cell carcinoma. These case illustrations emphasize the need to evaluate discordant lesions on dual-tracer PET/CT, which can lead to early diagnosis of second primary malignancies and thereby can provide better management in these patients.

前列腺癌双示踪PET/CT (68Ga-PSMA-11和18F-FDG)不一致病变的鉴别:第二原发恶性肿瘤的诊断

我们报告了2例转移性去势抵抗性前列腺癌，双示踪PET/CT (68Ga-PSMA-11和18F-FDG PET/CT)的病变不一致，随后的组织病理学评估显示第二原发恶性肿瘤合并肝细胞癌和胆管癌以及低分化鳞状细胞癌。这些病例强调需要在双示踪PET/CT上评估不一致的病变，这可以导致第二原发性恶性肿瘤的早期诊断，从而可以为这些患者提供更好的治疗。
