The laryngoscopy showed laryngeal oedema with narrowed laryngeal inlet with no glottic/supraglottic lesions or foreign bodies (Figure 1). Subsequently, a portable anterior-posterior chest X-ray showed widened mediastinal opacity (Figure 1). A contrast computerized tomography (CT) scan of the neck and chest showed massively dilated oesophagus to the level of cricopharyngeus, compressing the trachea with its narrowest diameter of 5 mm, displacing the trachea and larynx anteriorly (Figures 1 and 1).
