A 60-year-old man with metastatic prostate cancer presented with breast swelling for one year. Suspicious breast masses were identified in both breasts with mammography and ultrasound. Biopsy of both masses showed florid gynecomastia without malignancy. Sixteen months later, the patient underwent 18F-fluciclovine PET/CT for biochemical recurrence of prostate cancer; this showed focal radiotracer uptake in both breasts. Repeat mammogram and ultrasound showed these areas to correspond with the previously biopsied masses, which were stable. To our knowledge, this is the first reported case of gynecomastia mimicking malignancy on 18F-fluciclovine PET/CT.
一位 60 岁患有转移性前列腺癌的男性，因乳房肿胀就诊 1 年。乳房 X 线摄影术和超声检查均发现双侧乳房有可疑乳腺肿块。双侧肿块活检显示明显的男性乳房发育，无恶性肿瘤。16 个月后，患者因前列腺癌生化复发进行 18F-氟柳氯胺 PET/CT 检查；结果显示双侧乳房有局灶性放射性示踪剂摄取。重复乳房 X 线摄影术和超声检查显示这些区域与之前活检的肿块相对应，且肿块稳定。据我们所知，这是首例 18F-氟柳氯胺 PET/CT 显示男性乳房发育样表现酷似恶性肿瘤的病例报告。
