A Hoarse Child With a Neck Mass: Airway First
A 4-year-old boy is brought in with 3 weeks of progressive hoarseness, a 'hot potato' voice, and a new right-sided neck swelling. He has had low-grade fevers and poor appetite. He is afebrile now, saturating 97% on room air, with mild inspiratory stridor at rest that worsens when he cries. Examination shows a 2.5 cm tender right level II mass and bulging of the right posterior pharyngeal wall with deviation of the tonsil medially. Flexible nasolaryngoscopy shows a smooth submucosal fullness pushing the right pharyngeal wall medially; the vocal folds are mobile but the airway looks narrowed. He has no stridor at rest when calm, but the parents report noisy breathing during sleep.
1. What is your differential and immediate priority in this child?

The presentation - fever, unilateral neck mass, medial displacement of the pharyngeal wall, and stridor - is classic for a retropharyngeal or parapharyngeal abscess, with Lemierre syndrome (internal jugular vein thrombosis) and Kawasaki disease lower on the list.
Immediate priority: airway assessment and stabilization, not imaging first.
- Keep the child calm; avoid aggressive throat examination that can precipitate airway obstruction.
- Do not perform blind incision and drainage in the office.
- Obtain contrast-enhanced CT of the neck (the study of choice to distinguish cellulitis from abscess and to assess airway narrowing and vascular involvement), but only after ensuring the airway is secure and the child is monitored.
- IV antibiotics covering streptococci, staphylococci, and anaerobes (e.g., ampicillin-sulbactam or clindamycin) should be started promptly.
- Alert anesthesia and prepare for awakening intubation or tracheostomy if the airway is compromised; a child with stridor and a retropharyngeal collection is a difficult airway.
2. CT shows a 2.0 cm rim-enhancing retropharyngeal collection with mass effect on the airway. How do you manage it, and what complications do you watch for?

Management:
- Drainage is indicated for a collection >2 cm with airway compromise or failure to improve on antibiotics; intraoral transpharyngeal drainage is preferred for a retropharyngeal abscess in a child, performed in the operating room with airway control.
- Continue IV antibiotics for 10–14 days (longer if complications), transitioning to oral once afebrile and improving.
- Do not drain a retropharyngeal abscess transcutaneously unless it is lateral/parapharyngeal.
Complications to watch for:
- Airway obstruction and aspiration of pus.
- Lemierre syndrome: septic thrombophlebitis of the internal jugular vein with septic emboli; suspect if fevers persist or if there is neck tenderness along the vein - obtain Doppler ultrasound or CT venography and consider anticoagulation.
- Mediastinitis if the infection tracks inferiorly; obtain chest imaging if symptoms suggest it.
- Carotid involvement (rare) with pseudoaneurysm or rupture.
- Follow-up imaging is not routine if the child improves; repeat CT only for nonresolution.
