Can adults get Wilms tumor?

Wilms’ tumour in adults is extremely rare and has a poorer prognosis than paediatric Wilms’ tumour. It is difficult to differentiate adult Wilms’ tumour from renal cell carcinoma based on radiological findings alone. The diagnosis in adults is often serendipitous following nephrectomy for presumed renal cell carcinoma.

Can Wilms tumor be seen on xray?

Chest x-ray

Chest x-rays may be done to look for any spread of Wilms tumor to the lungs, as well as to have a baseline view of the lungs to compare with other x-rays that might be done in the future. This test might not be needed if a CT scan of the chest is done.
