A 28 year old male who complained of abdominal pain over the past several months was found on CT to have lymphadenopathy along the right aspect of the inferior vena cava. The patient was subsequently seen by an oncologist where further work up of the lymphadenopathy was performed. A MR of the abdomen demonstrated right aortocaval and para-caval lymph nodes measuring to 3.7cm. A testicular ultrasound was then performed, which demonstrated an apparent peripheral focal hypoechoic region with no associated internal vascularity within the right testes. Biopsy of the retroperitoneal lymph nodes pathologically confirmed the diagnosis of seminoma. Keywords: Seminoma, Testicular Cancer, Retroperitoneal Adenopathy, Oncology, Burned-Out Tumor.
