Thoracic asymmetries characterized by increased radiolucency of the lungs are important causes of morbidity in infants and children. Evaluation of affected patients frequently requires multiple imaging methods to diagnose the abnormality and to plan the surgical correction. The authors review and illustrate the characteristics of both common and rare thoracic asymmetries with emphasis on the radiological findings. The usefulness of different imaging methods in the diagnosis and treatment of these conditions is evaluated. The differential diagnosis as well the pitfalls and diagnostic difficulties are also discussed.
