However, recurrent or persistent stridor with dysphagia should raise concern for vascular anomalies (eg, aberrant right subclavian artery), bacterial tracheitis, epiglottitis, retropharyngeal abscess, foreign body aspiration, mediastinal tumors, or other compressive pathologies. Early symptomatic presentation with dysphagia and stridor in young children is unusual, as aberrant right subclavian artery symptoms typically develop after age 40. When clinical presentation deviates from typical croup, particularly if associated with dysphagia, ultrasound, magnetic resonance imaging, or contrast-enhanced CT can identify vascular anomalies.
