A child swallowed objects, initially thought to be a coin, but closer inspection revealed they mimicked a disk battery. This case highlights critical differences in managing ingested coins versus batteries and the importance of accurate radiograph interpretation.
Area of Science:
- Pediatric Gastroenterology
- Emergency Medicine
- Radiology
Background:
- Esophageal foreign body ingestion is common in children.
- Disk battery ingestion is a surgical emergency due to rapid tissue damage.
- Coin ingestion requires different management strategies than battery ingestion.
Observation:
- A 4-year-old asymptomatic child presented with suspected esophageal coin ingestion.
- Radiographic findings suggested disk battery ingestion, a critical surgical emergency.
- Surgical exploration revealed superimposed coins mimicking a disk battery.
Findings:
- Radiographic appearance can be deceptive, mimicking serious ingestions.
- Distinguishing between coin and disk battery ingestion is crucial for appropriate management.
- Superimposed coins can present a rare radiographic mimic of a disk battery.
Implications:
- Emphasizes the need for careful radiographic interpretation in suspected foreign body ingestions.
- Highlights critical differences in the emergency management of ingested coins versus disk batteries.
- Underscores the importance of surgical consultation for suspected disk battery ingestions.
