Overview
Ultrasound may be helpful in the diagnosis of wilms' tumor.
Ultrasound
- Ultrasound may be helpful in the diagnosis of wilms tumor.
- It is the best initial diagnostic study used in cases suspected with wilms tumor.
- Ultrasonography can help identify the mass as a kidney mass.
- It can distinguish tumor mass from other causes of renal swelling like hydronephrosis.
- Doppler ultrasonography can help to detect invasion of renal vein and IVC by the tumor.
- Doppler ultrasonography can be performed to detect tumor infiltration of the renal vein and inferior vena cava, and to assess patency of blood flow
Ultrasound is a very useful examination and in almost every situation will be the primary investigation of choice. It is helpful to localise the mass to kidney and also distinguish from other causes of renal masses (e.g. hydronephrosis). Although many of the features seen on CT/MRI can also be identified on US, the former are required to adequately stage the disease, and is established in protocols for Wilms tumour staging in North America and Europe 9 .
Doppler examination can be performed to examine the renal vein and IVC to assess for the presence of tumour thrombus.
Ultrasound is a very useful examination in so far as it can distinguish between a cystic mass (e.g. hydronephrosis) and a solid mass. Doppler examination should be performed to examine the renal vein and IVC to assess for the presence of tumour thrombus.[1]
