Double Coin Mimicking a Button Battery: a Rare Radiological Entity of an Esophageal Foreign Body

Ingestion of foreign bodies is a common entity in emergency clinical practice, especially in the pediatric population. Personal history is rather challenging in these patients, while it is important to accurately define the ingested foreign body. Therefore, the history of a caregiver/eyewitness, physical examination and radiographic findings are taken under consideration. Coins - in various places and alignments - are among the most common foreign bodies of the upper digestive tract, while a history or radiological findings of button batteries are indicating the need for immediate removal. We report a rare case of a seven-year-old boy with an esophageal foreign body, whose radiographic findings were intriguing, as they were suggesting a button battery digestion, while urgent esophagoscopy revealed a double coin ingestion perfectly aligned in the same place, opposing each other.
