Extramedullary multiple myeloma (EM) has negative prognostic implications on the overall survival as well as progression-free survival. Testis is a rare site of EM, which can be a part of diffuse involvement in multiple myeloma or a site of recurrence in patients with remission. We present a case of EM of testes and left spermatic cord in an 80-year-old man who presented with painless progressive enlargement of the scrotum. F-FDG PET/CT revealed tracer avidity of both testes and left spermatic cord. Bilateral radical orchidectomy was subsequently performed, and the diagnosis of multiple myeloma was confirmed on histopathology.
髓外多发性骨髓瘤（EM）对总生存和无进展生存均有不良预后意义。睾丸是 EM 的罕见部位，它可以是多发性骨髓瘤弥漫性累及的一部分，也可以是缓解后患者复发的部位。我们报告一例 80 岁男性患者，因阴囊无痛性进行性肿大就诊，其双侧睾丸和左侧精索均有 F-FDG PET/CT 摄取。行双侧根治性睾丸切除术，组织病理学证实为多发性骨髓瘤。
