Large, well-defined isodense lesion noted in the right suprarenal region on the non contrast series. It displaces the right kidney inferiorly. Fat planes with right kidney are well maintained.
Post contrast study shows progressive arterial enhancement with a few central non enhancing areas (likely representing areas of necrosis). Branches from the right renal artery and right inferior phrenic artery can be seen feeding the tumour. The tumour invades the inferior vena cava on the post contrast images. The infrarenal segment of the inferior vena cava is not opacified in portal venous phase.
