Testicular metastasis from prostate cancer is rarely reported in radiology literature. We present the case of an 84-year old man with history of prostate cancer, who obtained an 18 F-Pylarify PET/CT for biochemical recurrence, with an incidentally detected prostate-specific membrane antigen-avid large right testicular mass. The 18 F-Pylarify PET/CT showed no evidence of local prostate tumor recurrence in the prostate bed, but demonstrated small right common and external lymph node metastases in addition to the incidentally noted large right testicular mass. The patient underwent orchiectomy with subsequent histopathologic examination confirming metastasis from prostate cancer.
前列腺癌的睾丸转移在放射学文献中很少报道。我们报告了一例 84 岁男性，有前列腺癌病史，因生化复发接受 18 F-Pylarify PET/CT 检查，偶然发现右侧睾丸前列腺特异性膜抗原阳性的巨大肿块。18 F-Pylarify PET/CT 检查未发现前列腺床局部前列腺肿瘤复发，但除了偶然发现的右侧巨大睾丸肿块外，还显示右侧常见和外部淋巴结转移。患者接受了睾丸切除术，随后的组织病理学检查证实为前列腺癌转移。
