Overview
CT scan is a useful tool to determine stage based on tumor size and structures involved.
CT
Wilms tumours are heterogeneous soft-tissue density masses with frequent areas of calcification (~10%) and fat-density regions. Enhancement is also patchy, and allows for better delineation of the relationship between the mass and kidney. 20% of cases have lung metastases at time of diagnosis.
CT scan shows a renal mass which often shows one or more of the following: areas of hemorrhage, invasion of surrounding organs, thrombus in or occlusion of the renal vein and/or the inferior vena cava, abdominal lymph nodes and contralateral involvement. 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. [1][2]
