Renal arterial cut-off sign

Renal arterial cut-off sign, as the name suggests, is an abrupt termination of the contrast-opacified lumen of the renal artery. It may or may not be associated with contrast extravasation.

It is seen in a vascular injury, e.g. segmental or main renal artery thrombosis or occlusion.
