Stiff Neck and Drooling in a Young Girl.

A 3-year-old girl was brought to the emergency department 4 days after she was playing with a button battery and subsequently had a choking episode. The patient was seen immediately at a different emergency department and was discharged home after a normal chest x-ray finding and able to tolerate an oral challenge with liquids. She was later evaluated by her primary care physician and started on amoxicillin for possible pharyngitis. On examination in our emergency department, the patient had pooling of secretions and was unwilling to range her neck due to pain. Soft tissue neck x-ray confirmed a 20-mm button battery in the esophagus with air lucencies in the prevertebral soft tissues.
