(A) Portable chest radiograph showing extensive subcutaneous tissue emphysema of the cervical and thoracic region (black arrows), with pneumomediastinum (arrow head) and pneumoperitoneum (white arrows). (B and C) Chest-abdominal computed tomography axial image and coronal plane reconstruction with lung window, showing, as in the chest radiograph, subcutaneous tissue emphysema dissecting the muscle planes of the cervicothoracic region (black arrows), minimal left apical laminar pneumothorax (black arrow head), pneumomediastinum (white arrow head), and moderate pneumoperitoneum (white arrows), with no evidence of perforated hollow viscus.
