Subcutaneous metastases are rare in prostate cancer. Herein, we present a case of a 66-year-old man with prostate cancer, who underwent 68 Ga-labeled DOTA-ibandronic acid ( 68 Ga-DOTA-IBA) PET/CT to explore the possibility of 177 Lu-DOTA-IBA treatment. 68 Ga-DOTA-IBA PET/CT demonstrated intensely increased uptake in the multiple osteoblastic bone metastases. Unexpectedly, 68 Ga-DOTA-IBA uptake in multiple subcutaneous metastases was also noted.
前列腺癌中皮下转移较为罕见。在此，我们报告一例 66 岁前列腺癌患者，为探索 177 Lu-DOTA-IBA 治疗的可能性，行 68 Ga 标记的 DOTA-伊班膦酸（68 Ga-DOTA-IBA）PET/CT 检查。68 Ga-DOTA-IBA PET/CT 示多发成骨性骨转移灶摄取明显增加。出乎意料的是，还观察到多个皮下转移灶摄取 68 Ga-DOTA-IBA。
