A CTA projected in the coronal plain (image A) shows a moderately high grade stenosis of the left renal artery (arrow). Image B is an axial CT scan through the kidneys of a second patient and shows a moderate stenosis of the left renal artery (arrow), a small left kidney with a thin cortex (arrowhead), and a small left accessory renal artery (dashed arrow).
