1. Seminoma is the most common pure germ cell tumor of the testis, accounting for 35-50% of all germ cell tumors. A rare subtype of seminomas, spermatocytic seminoma, affects an older patient population than classic seminoma. 2. The typical sonographic appearance of testicular seminoma is a hypoechoic mass with vascular flow. As seminomas enlarge, the hypoechoic mass can take on a nodular appearance with intervening echogenic septations. 3. Testicular seminoma commonly spreads via the lymphatics to the retroperitoneal lymph nodes. The lymphadenopathy may be homogeneous in appearance or may show necrosis, calcification and even result in hydronephrosis or vascular invasion. 4. Supernumerary and undescended testes are at increased risk of developing a seminoma. Masses within the inguinal canal or pelvis in a male patient should prompt the reader to examine the scrotum for bilateral spermatic cords.

1. Introduction 2. Multimodality imaging of seminoma and rare variants with gross and histologic radiologic pathologic correlation. 3. Imaging of the variable appearances of seminoma-related lymphadenopathy, with gross and histologic radiologic pathologic correlation. 4. Imaging of seminomas arising in supernumerary and undescended testes.
