Infant with hematemesis who had an unsuccessful nasogastric tube placement

CXR of esophageal perforation from nasogastric tube placement
CXR AP shows air outlining the heart in the pericardial space, air outlining the thymus in the mediastinum, and air in the bilateral pleural spaces.

The diagnosis was pneumopericardium, pneumomediastinum, and pneumothorax due to esophageal perforation from traumatic nasogastric tube placement. A subsequent esophagram did not demonstrate a leak.
