The contrast-enhanced computed tomography (CT) sections through midabdomen show a heterogeneously enhancing mass (arrow) occupying the interpolar region of the left kidney. The mass is centered in the renal parenchyma and causes contour deformity of the kidney. It is not surrounded by a dilated collecting system. No involvement of neighboring structures is seen. No lymphadenopathy is seen in these sections. Left renal (arrowhead) vein is well seen and shows no enlargement or obvious filling defect.
