Premature newborn after nasogastric tube placement

CXR of nasogastric tube placement into lung resulting in tension pneumothorax
Initial CXR AP (left) shows the course of the nasogastric tube to project over the right lung and the tip of the nasogastric tube projects over the liver and is probably in the right costophrenic sulcus. The remaining tubes and lines are in appropriate position. CXR AP obtained after removal of the nasogastric tube (right) shows a large amount of air in the right pleural space and there is mediastinal shift to the left.
