Chest Wall Disorder: Pectus Carinatum

Also called: Pigeon Breast or Pigeon Chest

What Is Pectus Carinatum?

Pectus carinatum is a chest wall problem where the front of the chest sticks out more than it should. It happens when the ribs and breastbone (sternum) grow outward more than usual.

The condition mostly affects boys and usually gets worse during adolescence, especially during growth spurts and the teen years. It doesn't go away on its own, but treatment with a chest brace is usually successful.
