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.
