1 Frontal view of the chest showing a coin at the thoracic inlet
Frontal view of the chest showing a coin at the thoracic inlet. When an FB gets lodged in the trachea, the orientation of the FB is opposite that seen with an esophageal FB. With the configuration of the tracheal rings and with incomplete cartilage posteriorly, a coin in the trachea appears in the sagittal orientation (ie, the coin is seen from the side) in a frontal view (A), and in the coronal orientation (ie, the coin is seen as a disk) on a lateral view (B). However, as seen here, this rule is not always correct. These radiographs actually show an impacted esophageal coin that mimics the orientation that is classically seen with a coin lodged in the trachea. (Photo contributor: Binita R. Shah, MD.)
