There are extensive and numerous areas of wedge-shaped perfusion defects throughout the left renal cortex. There is perinephric and retroperitoneal hemorrhage. There is apparent irregularity of the left renal arterial pedicle seen on the portal venous phase images, suggesting intimal injury. Abdominal reformatted images were generated from the portions of the abdomen included on the arterial phase chest, which includes the left renal artery. This provides greater characterization of left renal arterial injury, which is irregular and may have a small dissection flap present (the injury and degree of narrowing is best appreciated on coronal reformatted images).
