Abdominal pain.

Patient Data

Age: 35 years
Gender: Male
ultrasound

Normal right testicle, 2 left testicular masses, a smaller partially calcified mass, and a larger hypoechoic mass.

Left adrenal mass, conglomerate retroperitoneal lymphadenopathy, left renal vein thrombosis with extension into the IVC. Multiple indeterminate low-density liver lesions.

Case Discussion

The left testicle was removed and the larger left testicular mass was proven to be a seminoma. Remember that the testicles arise in the retroperitoneum and descend into the scrotum, dragging their blood supply and lymphatics with them. That is why testicular lymph flow is to retroperitoneal lymph nodes, which explains the location of the lymphadenopathy in this case.
