Primary prostate mucinous adenocarcinoma is an exceedingly rare entity with distinct imaging characteristics. We report the case of a 62-year-old man with biopsy-proven prostate mucinous adenocarcinoma. The patient underwent MRI and multi-tracer PET/CT. PET/CT images demonstrated the prostate lesion with moderate uptake of 68 Ga-PSMA and 68 Ga-FAPI, yet significantly high 18 F-FDG uptake. No abnormal radiotracers' uptake was observed elsewhere in the body. Multi-tracer PET/CT findings suggest that 18 F-FDG may be a more suitable radiotracer for the systemic assessment of primary prostate mucinous adenocarcinoma.
原发性前列腺黏液腺癌是一种极为罕见的疾病，具有独特的影像学特征。我们报告一例经活检证实为前列腺黏液腺癌的62岁男性病例。该患者接受了MRI和多示踪剂PET/CT检查。PET/CT图像显示前列腺病变对68Ga-PSMA和68Ga-FAPI有中度摄取，但18F-FDG摄取显著增高。身体其他部位未观察到放射性示踪剂的异常摄取。多示踪剂PET/CT检查结果表明，18F-FDG可能是对原发性前列腺黏液腺癌进行全身评估更合适的放射性示踪剂。
