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]
  • CT scan of the renal mass can further reveal:
  • 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]
