Button battery esophageal impaction

Case contributed by Dr David Chang


Presents with his mother with irritability, coughing, and rhinorrhoea.

Patient Data

Age: 1 year
Gender: Male

A foreign body is seen at the level of the cricopharyngeus.  A halo sign or double ring sign can be seen which eludes towards the foreign body being a button battery.  On the lateral view the foreign body can be seen impacted in the esophagus with the trachea seen anteriorly.  

Case Discussion

This case demonstrates a classic finding of impaction of a button battery in the cervical esophagus.  Differentiation between a button battery and other foreign bodies is of the utmost importance.  Ingestion and impaction of a button battery can cause respiratory distress through obstruction and a caustic burn.  If the battery is impacted as seen in this case, significant morbidity and/or mortality can occur within 8 hours after ingestion.  

Button batteries if passed through the stomach pose minimal risk for impaction or burns and can be observed until passed in the stool.
