A chest CT scan confirmed the radiological findings and revealed the presence of a large pneumomediastinum (Figures 1 and 2) and an overinflated tracheal tube cuff (maximum diameter: 4 cm); the cuff pressure was 20 cmH20.
Neck CT. An overinflated tracheal tube cuff and dilated trachea can be seen compressing the cervical esophagus.

A chest CT scan confirmed the radiological findings and revealed the presence of a large pneumomediastinum (Figures 1 and 2) and an overinflated tracheal tube cuff (maximum diameter: 4 cm); the cuff pressure was 20 cmH20.
Postoperative neck CT. A neck CT obtained on postoperative day 10 shows no free air between the trachea (arrow) and the esophagus (arrowhead) at the level of the tracheoesophageal fistula repair (above the tracheostomy).
