Pectus excavatum commonly presents with which features?

• A. Chest asymmetry with shortness of breath and possible mitral valve prolapse murmur
• B. Acute chest pain with pleural effusion
• C. Wheezing only with exertion and chest wall warmth
• D. Asymptomatic chest wall lump without cardiopulmonary signs

Answer: (A)

Pectus excavatum is a chest wall deformity where the sternum sinks inward, creating visible chest asymmetry. This inward flattening reduces the front-to-back dimension of the thoracic cavity, which can limit lung expansion and, as the heart is displaced by the deformity, may cause symptoms like shortness of breath with activity. In some individuals, especially those with associated connective tissue issues, this heart displacement can be linked to a mitral valve prolapse murmur. So the combination of chest asymmetry, exertional shortness of breath, and a possible mitral valve prolapse murmur fits the typical clinical picture of this condition. Other descriptions don’t align as well with what pectus excavatum usually presents. Acute chest pain with pleural effusion points to a separate acute thoracic process. Wheezing only with exertion plus chest wall warmth isn’t characteristic of a structural chest wall deformity. An asymptomatic chest wall lump would imply a mass-like lesion rather than the sunken sternum and often would not include the cardiopulmonary signs seen with pectus excavatum.
