Pectus excavatum may be associated with which condition?

• A. Marfan Syndrome or scoliosis
• B. Turner syndrome
• C. Cystic fibrosis
• D. Bronchiectasis

Answer: (A)

Pectus excavatum commonly appears with disorders that affect connective tissue and skeletal structure. In Marfan syndrome, for example, a defect in connective tissue leads to chest wall deformities and a higher tendency for scoliosis, so pectus excavatum fits into this pattern. The presence of scoliosis with a chest wall depression reflects the broader skeletal abnormalities seen in Marfan, where the thoracic cage can be shaped by weakened connective tissue and abnormal growth patterns. Turner syndrome, while associated with various body features, does not have pectus excavatum as a classic or defining association. Cystic fibrosis and bronchiectasis are primarily pulmonary diseases; they affect the lungs and airways rather than causing the chest wall deformity seen in pectus excavatum, and they aren’t characteristically linked to this chest wall condition.
