Join us as we navigate through the clinical landscape of RPA, providing not only a detailed analysis of the presented case but also valuable takeaways for professionals in the field and those aspiring to enter the world of pediatric intensive care. Welcome to PICU Doc On Call – where MED-ED meets the real challenges of the PICU.

• Patient: 9-month-old male with rapid symptom onset, left neck swelling, fever, noisy breathing, and decreased oral intake.
• Initial presentation: Left neck swelling, limited neck mobility, and deteriorating condition.
• Imaging: Neck X-ray and CT scan with IV contrast confirmed Retropharyngeal Abscess (RPA).
• Management: High-flow nasal cannula, intravenous antibiotics, and consultation with ENT. PICU admission for comprehensive care.

• Rapid Symptom Onset
• Neck Swelling & Drooling
• Limited Neck Mobility

• A previously healthy 9-month-old male with a recent upper respiratory infection, presenting with rapid-onset left neck swelling, fever, and respiratory distress. Imaging suggestive of a Retropharyngeal Abscess, requiring urgent PICU management for airway protection and antibiotic therapy.

• Anatomy of retropharyngeal space
• Rapid communication of infections via lymph nodes
• Infection sources: dental issues, trauma, localized infections (e.g., otitis, URI)

• Airway compromise and posterior mediastinitis
• Progression from cellulitis to abscess
• Microbial suspects: Group A Streptococcus, anaerobes, Staphylococcus aureus, Haemophilus influenza, Klebsiella, Mycobacterium avium-intracellulare

• Seen predominantly in children aged 3-4 years
• Non-specific symptoms in the acute setting
• Pronounced symptoms in PICU: neck pain, stiffness, torticollis, muffled voice, stridor, respiratory distress
