title: CT demonstration of "chicken trachea" resulting from complete cartilaginous rings of the trachea in ring-sling complex.
abstract: We report a 10-month-old infant who presented with tetralogy of Fallot and respiratory disease in whom the suspicion of a ring-sling complex was confirmed by high-resolution CT. CT demonstrated the typical association of left pulmonary artery sling and the "chicken trachea" resulting from complete cartilaginous rings of the trachea.
