A 2-year-old child is brought to the clinic with wheezing after a cookout episode; the clinician suspects which diagnosis?

• A. Vascular ring
• B. Foreign body aspiration
• C. Bronchiolitis
• D. Reactive airway disease

Answer: (B)

When a young child develops wheeze immediately after a choking incident during eating, foreign body aspiration is the most likely explanation. A piece of food inhaled during a cookout can lodge in a bronchus and partially block airflow, causing wheeze that is often localized to one side and may be accompanied by reduced breath sounds. This abrupt onset after a specific eating event fits a sudden airway obstruction from an inhaled object far more than a viral illness or a chronic reactive airway pattern. Compared with other possibilities, vascular ring usually causes noisy breathing or stridor and feeding difficulties rather than sudden unilateral wheeze after a meal. Bronchiolitis is a viral infection with fever, diffuse crackles or wheeze, and a more gradual course rather than an event-triggered onset. Reactive airway disease (asthma) can cause wheeze but typically presents with recurrent episodes over time and not an abrupt, localized obstruction after choking. If suspicion is high, the priority is to assess and secure the airway if needed, obtain imaging (recognizing that an initial radiograph can be normal if the object is radiolucent), and arrange urgent bronchoscopy, which serves both diagnostic and therapeutic roles to remove the foreign body.
