Diagnostic Considerations

Diagnosis of pectus carinatum is clinical and is based on descriptive findings identified during the physical inspection of the chest. It may occur as an isolated anomaly, in association with congenital heart disease, or with another skeletal anomaly (20% scoliosis). Mixed deformities can be observed in Poland syndrome. Approximately 25% of patients have a positive family history of chest wall deformity. Less frequently, pectus carinatum has been associated with Morquio syndrome, hyperlordosis, and kyphosis.
