Definition Pectus excavatum describes an abnormal formation of the rib cage that gives the chest a caved-in or sunken appearance. Alternative Names Funnel chest Considerations Pectus excavatum is a congenital (present at birth) abnormality that can be mild or severe. It is caused by too much growth of the connective tissue that joins the ribs to the breastbone. This causes the sternum to malform inward.

If pectus excavatum is severe, it may affect the heart and lungs, making exercise difficult. Also, the appearance of the chest may cause psychological difficulty for the child.

Common Causes Pectus excavatum will often occur by itself without any family history or other defects or problems. Other causes include: Familial pectus excavatum Marfan syndrome Poland syndrome Rickets
