Overview

Abdominal and pelvic CT scans may be diagnostic of seminoma. CT scan may detect metastases of seminoma to the para-aortic, inguinal or iliac lymph nodes. Visceral metastas is may observed.Chest CT is indicated when CXR is abnormal regional para-aortic lymph node spread is present.

CT

• Abdominal and pelvic CT scan may be helpful in the diagnosis of seminoma. Findings on CT scan diagnostic of seminoma include:
  • Retroperitoneal lymph nodes
  • Metastases to the para-aortic lymph nodes (It is the first site of spread lymphatic drainage at the level of the renal vessels)
    • Bulky nodal
    • Density homogenous,
    • Tend to encase surrounding vessels
  • Inguinal or iliac lymph node metastases suggest:
    • lymphatic spread by the scrotum
    • local tumor extension further the tunica vaginalis
  • Visceral metastases
  • Chest CT is indicated when:
    • CXR is abnormal
    • Regional para-aortic lymph node spread is present
