Fig. 8

Coronal inspiratory (A) and expiratory (B) volume-rendered CT images show severe expiratory tracheal collapse (long arrows) indicating tracheomalacia at thoracic inlet level. Longitudinal extent of focal tracheomalacia is nicely illustrated on expiratory-phase 4D CT image (B). Remnant of ligated tracheoesophageal fistula (short arrows) is noted.
