Summary
Food allergies, particularly to nuts, can mimic foreign body aspiration in children presenting with upper airway obstruction. Early consideration of food allergy is crucial for accurate diagnosis and timely treatment.
Area of Science:
- Pediatric Allergy
- Emergency Medicine
- Otolaryngology
Background:
- Allergic reactions to common foods like peanuts and tree nuts can manifest as life-threatening upper airway obstruction.
- Accurate diagnosis is critical as symptoms can overlap with other emergent conditions.
Observation:
- A case of allergic reaction to cashew was initially misdiagnosed as foreign body aspiration.
- This highlights the potential for confusion in clinical presentation.
Findings:
- When upper airway obstruction is the primary symptom of food allergy, it can be mistaken for foreign body aspiration.
- Peanut and tree nut allergies are frequent causes of both food allergy and foreign body aspiration in children.
Implications:
- Clinicians should include food allergy in the differential diagnosis for pediatric upper airway obstruction.
- Considering both food allergy and foreign body aspiration is essential for children presenting with airway compromise.
