Genitourinary
CT of Wilms tumor
Axial CT with contrast of the abdomen (above) shows a large non-calcified and non-enhancing mass crossing the midline with multiple retrocrural lymph nodes present. Axial CT (below) shows the mass is arising from the upper pole of the right kidney. The right renal vein and inferior vena cava are not clearly seen.

The diagnosis was Wilms tumor of the right kidney with probable tumor invasion of the right renal vein and inferior vena cava.
