Infant who has just been intubated

CXR of esophageal intubation
CXR AP (above) shows nasogastric tube with its tip within a distended stomach. An endotracheal tube is present to the right of the nasogastric tube and is projecting over an air-distended esophagus. There is near-complete atelectasis of the right lung. CXR AP (below) after reintubation now shows the endotracheal tube to the left of the nasogastric tube and interval resolution of the esophageal and gastric distension.

The diagnosis was esophageal intubation causing massive distension of the esophagus and stomach.
