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 suggestive of Wilms tumor include:[1][2][3]
    • Heterogeneous soft-tissue density masses
    • These masses have frequent areas of calcification (~10%) and fat-density regions
    • Lymph node metastasis
    • Invasion of surrounding organs
    • Thrombus in or occlusion of the renal vein and/or the inferior vena cava
    • Abdominal lymph nodes and contralateral involvement
    • Estimate tumor size and volume and to plan surgical management
    • Determine stage based on tumor size and structures involved
