Interval placement of a nasogastric tube with the tip positioned within the stomach. The distal esophageal segment of the tube is laterally displaced toward the left, with a crescentic opacity noted in the left paraspinal region of the retrocardiac space. This may represent the normal course of the esophagus or a hiatal hernia; however, a mediastinal or paraspinal hematoma cannot be excluded.
