case_images: A chest X-ray showed a slightly widened mediastinum with pleural effusion (Figure 1A). An ECG revealed widespread ST-elevation (Figure 1B).
case_images: (A) Coronal, (B) sagittal, and
  (C-H) axial chest CT images on arrival.. Note: A large volume of gas had collected (arrowhead) with an abscess
  (arrow) in the submandibular space, anterior neck space, and the upper and
  anterior mediastinum.

case_images: Contrast-enhanced CT images revealed that a large volume of gas had collected in the neck and upper and anterior mediastinum (Figure 2A-F). In addition, an abscess had formed in the retropharyngeal, bilateral sub-mandibular, upper paratracheal, and mediastinal spaces with pleural effusion and atelectasis in the right lower basal lobe (Figure 2B-H).
case_images: Pathological findings of excised skeletal muscle and fascia.. Notes: (A-C) Acute inflammation
  with necrosis, consistent with necrotizing fasciitis; (D) Gram
  staining revealed a large number of Gram-positive cocci.

case_images: Pathological findings from the excised skeletal muscle and fascia indicated acute inflammation with necrosis (Figure 3A-C), consistent with necrotizing fasciitis, and a large number of Gram-positive cocci were observed (Figure 3D).
