On Call Radiology - common radiology findings on call and in the Emergency Room and during the nightshift

Chapter: Chest (Read entire chapter)

Subchapter: Foreign body

Diagnosis: Coin in esophagus

Don't be confused by all the other lead buttons! There is a coin shaped foreign body projecting over the lower neck. On the lateral view it projects over the esophagus/trachea. However, it HAS to be in the esophagus, because it is en face on the PA view. If it would be in the trachea it would be en face on the lateral vie. The reason is, that the posterior wall of the trachea is membranous and has the least resistance, allowing the esophagus to orient in a AP position. Once again: en face on the PA view: in the esophagus - en face on the lateral view: in the trachea.
