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:[1][2]
- 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
