Abstract
<p>We report a case of bilateral synchronous testicular tumors, which was difficult to differentiate from malignant lymphoma. A 56-year-old man with a left scrotal mass was referred to our hospital. Ultrasonography revealed a uniformly hypoechoic mass in bilateral testes. Magnetic resonance imaging also revealed a homogeneously low-intensity lesion in the bilateral testes on T2-weighted images. Abdominal and chest computed tomography showed no lymphadenopathy or metastasis. The image findings at that time suggested a malignant lymphoma, and consequently, we performed a right radical orchiectomy. Histopathological examination revealed typical seminoma in the right testis; following this observation, left radical orchiectomy was performed, and the patient was diagnosed with synchronous bilateral testicular germ cell tumors. No recurrence or metastasis has been detected postoperatively. We recommend that the diagnosis of bilateral testicular tumors be made on the basis of patients' age, tumor marker level, and image findings.</p>
