Congenital chest wall malformation causing concave chest is called?

• A. Pectus excavatum
• B. Pectus carinatum
• C. Flail chest
• D. Scoliosis

Answer: (A)

Pectus excavatum, also known as funnel chest, is a congenital chest wall deformity where the sternum and adjacent costal cartilage grow inward, producing a concave or sunken appearance of the chest. This makes it the classic example of a concave chest. Pectus carinatum would cause a protruding or bow-shaped chest, flail chest results from trauma with paradoxical chest wall movement, and scoliosis is a lateral curvature of the spine that can distort the thorax but is not a primary chest wall concavity.
