pectus carinatum

Last reviewed 01/2018

Pectus carinatum describes a deformity of the chest wall in which there is an outward bowing of the sternum. It is often considered a congenital condition though it is probably acquired as a result of childhood respiratory illness or rickets.

Pectus carinatum is caused by an upward curving of the lower costal cartilages, usually the fourth to eighth, which push the sternum forward. It is less common than pectus excavatum.

The condition is benign and usually asymptomatic.

Surgical correction is possible.
