CT neck and chest show gas in retropharyngeal, prevertebral and perivisceral space extending inferiorly to base of neck and superior mediastinum anteriorly with scattered locules of gas at the right base of tongue and anterior strap muscles. There is also a thin curvilinear lucency posterior to upper intrathoracic oesophagus and contour irregularity of the supraglottic larynx with locules of gas.
These findings are suspicious for oesophageal and tracheal injury.
