case_images: (a) Arterial contrast-enhanced CT demonstrates acute aortic dissection, without renal ischemia. True (*) and false lumens, contrast opacified. (b) Venous CT demonstrates LRV compression between the enlarged aorta and SMA (arrow) with distal dilatation. Hepatic cysts are also shown

case_images: On the retrospective review of CT scans, the arterial phase demonstrated the left renal artery originating from the true lumen of the aorta and no apparent renal ischemia [Figure 1a]. The venous phase showed compression of LRV between the enlarged aorta and SMA with distal dilatation [Figure 1b].
case_images: Three-dimensional CT imaging demonstrates compression of LRV (black arrow) between the aorta and SMA (white arrowhead). A prominent left gonadal vein (black arrowhead), implicating formation of collateral circulation, is also noted
