We report a case of a 62-year-old man with biochemical recurrence of prostate cancer disease, investigated by fluorine-18-Choline ((18)F-FCH) PET/CT. (18)F-FCH PET/CT demonstrated focal increased uptake of (18)F-FCH inside the right testis, suggestive for distant recurrent disease. On testis removal, a Leydig cell tumor of 2.5 cm in diameter was unexpectedly found. (18)F-FCH PET/CT may demonstrate tumors other than prostate cancer.
我们报告了一例 62 岁男性前列腺癌疾病生化复发的病例，该病例通过氟-18-胆碱 ((18)F-FCH) PET/CT 进行了检查。(18)F-FCH PET/CT 显示右侧睾丸内（18）F-FCH 摄取增加，提示远处复发疾病。在睾丸切除时，意外发现一个直径为 2.5 厘米的莱迪希细胞瘤。(18)F-FCH PET/CT 可能会显示除前列腺癌以外的肿瘤。
