Radiographic identification of ingested disc batteries

Area of Science:

• Radiology
• Gastroenterology
• Pediatrics

Background:

• Accidental ingestion of disc batteries is a growing concern, leading to severe esophageal injury.
• The caustic nature of leaking battery contents (sodium or potassium hydroxide) causes rapid tissue damage.

Observation:

• Disc batteries lodged in the esophagus present unique radiographic findings.
• Anterior projections reveal a double density shadow due to the battery's bilaminar structure.
• Lateral views show rounded edges and a distinct step-off at the cathode-anode junction.

Findings:

• Radiographic signs aid in differentiating disc batteries from other esophageal foreign bodies, such as coins.
• The double density and step-off are key identifiers distinguishing batteries from coins, which lack these features.

Implications:

• Accurate and rapid radiographic identification of esophageal disc batteries is crucial for timely medical intervention.
• Recognizing these signs can prevent significant morbidity and mortality associated with esophageal burns.
