Frontal radiograph showing the most life-threatening finding of right-sided tension pneumothorax with left-sided mediastinal shift; this should be immediately decompressed. Extensive left-sided subcutaneous emphysema is also featured. However, another pertinent finding is of a well-defined structure over the left hemithorax midzone which appears to be 'lifted' off the left heart border. This is the angel wing or spinnaker sign representing the pediatric thymus in pneumomediastinum.
Nasoenteric tube is correctly placed in the stomach.
