CXR AP (above left) shows the chest to be unremarkable aside from a right sided aortic arch. However, there is no air seen within the gastrointestinal tract. CXR lateral (above right) shows the proximal esophagus behind the trachea to be very dilated. CXR obtained after placement of a nasogastric tube (below) shows the nasogastric tube to be looped within the proximal esophagus.
