Overview
Abdominal CT scan may be helpful in the diagnosis of Wilms tumor.Findings on CT scan which can be suggestive of Wilms tumor include soft-tissue density masses, areas of calcification (~10%) and fat-density regions. CT is better than ultrasonography in detecting small lesions of tumor. CT scan of the chest can be helpful to diagnose lung metastasis.
CT scan
- Abdominal CT scan may be helpful in the diagnosis of Wilms tumor.
- Findings on CT scan which can be suggestive of Wilms tumor include:[1]
- Heterogeneous soft-tissue density masses
- These masses have frequent areas of calcification (~10%) and fat-density regions
- Lymph node metastasis
- CT scan of the renal mass can further reveal:
- Invasion of surrounding organs
- Thrombus in or occlusion of the renal vein and/or the inferior vena cava
- Abdominal lymph nodes and contralateral involvement
- CT is better than ultrasonography in detecting small lesions of tumor.
- CT scan of the chest can be helpful to diagnose lung metastasis. [2]
- A preoperative CT scan helps to better estimate tumor size and volume and to plan surgical management more successfully.
- It is a useful tool to determine stage based on tumor size and structures involved.[3]
