Reduction of the diameter of the aortic-mesenteric compass, which measures 3.4 mm in the anteroposterior diameter. In addition, there is a reduction in the caliber of the left renal artery and the duodenum. In liver segment VI, a hypodense pseudonodular image is visualized, measuring 11 mm, which presents peripheral and nodular enhancement after the administration of intravenous contrast, a finding that suggests hepatic hemangioma.

Case Discussion

The superior mesenteric artery syndrome or also called Wilkie's syndrome is due to the decrease in the aortomesenteric distance and the decrease in the aortomesenteric angle. This condition can compress the duodenum or renal vessels.

Normal values:

  • aortomesenteric distance: 10-28 mm.
  • aortomesenteric angle: 25º-60º.
