A pectus carinatum (otherwise known as a pigeon chest) refers to a chest wall deformity in which the sternum protrudes anteriorly. It is less common than pectus excavatum.
Patients may present with dyspnoea and exercise intolerance.
Familial occurence is reported in approximately 25%.
A pectus carinatum may be demonstrated on lateral chest radiographs or cross-sectional imaging of the chest. There are two patterns of sternal protrusion :
- chondro-gladiolar : protrusion of the middle and lower sternum, and
- chondro-manubrial : protrusion of the manubrium and upper sternum. This is a less common variant, and is also known as the Currarino-Silverman syndrome.
