History: Child with reported swallowed foreign body.
Battery: Frontal radiograph of the abdomen shows a metallic foreign body in the stomach (yellow arrow). Note the beveled edges, compatible with a swallowed battery.
This is a case of a swallowed battery, which is an urgent finding that needs to be reported immediately to the referring clinician for endoscopic removal. Read about distinguishing batteries from other similar appearing foreign bodies such as coins here. Below is a penny in the esophagus.
Penny in Esophagus: Frontal radiograph of the chest reveals a round radiopaque foreign body of metallic density projecting over the upper thoracic spine. Of note, the air filled trachea projects to the right of the foreign body and the lungs are clear and well expanded (indicating the foreign body is likely not obstructing the airway).
