Chest x-ray of a 12-year-old boy demonstrates slight indentation of aorta (figure of 3 sign) with associated inferior rib notching.

Arrows identify prominent inferior rib notching due to enlargement of intercostal arteries.

Case Discussion

Aortic coarctation can be difficult to identify on chest x-ray and routine review of aortic outline, as well as the ribs, is necessary if one is to make the diagnosis.
