Figure 1
Initial CT scan showing extensive emphysema in the oropharynx, neck, and mediastinum. Red arrows indicate the location of the sagittal plane subcutaneous emphysema. Emphysema in the horizontal plane: (a) nasopharyngeal emphysema; (b) oropharyngeal emphysema; (c) laryngeal emphysema; (d) upper mediastinal emphysema; (e) bronchial emphysema; (f) subbronchial emphysema; (g) diaphragmatic emphysema. In the coronal plane, the red circles indicate parapharyngeal emphysema, and the red squares indicate peritracheal emphysema. CT, computed tomography.

Figure 2
Follow-up imaging demonstrating resolution of emphysema after treatment. Red arrows indicate the location of the sagittal plane subcutaneous emphysema. Emphysema in the horizontal plane: (a) a small amount of emphysema is visible in the parapharyngeal space of the larynx; (b) no emphysema in the upper mediastinal space; (c) no emphysema in the suprabronchial space; (d) no emphysema in the subbronchial space; (e) no emphysema in the diaphragmatic space. In the coronal plane, the red circle indicates parapharyngeal emphysema.
