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. 18F-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.
