FIG 2. CT scans obtained in patient 3, a 54-year-old man.
A and B, Coronal scans show ASA (small white arrow) and AKA (black arrows). Thorough inspection reveals that the top of the hairpin curve is visualized at the upper edge of the scan. The continuity of the 10th intercostal artery (large white arrow), spinal branch (curved white arrow), and radiculomedullary artery (black arrows) is obscure because of close attachment of these vessels to the bone as a result of narrow intervertebral foramen.
