P CBD RETROPHARYNGEAL TEAR

 A

Here’s a structured case discussion for the scenario you provided:

---

Case Summary

• Patient: 2-year-old boy, previously healthy

• Presenting complaints:

  • 2-day history of dysphagia

  • Refusal to eat or drink

  • Drooling (unable to swallow saliva)

  • Refusal to speak

  • Limited neck movement (refuses to look up or turn neck)

---

Key Clinical Features / Red Flags

1. Drooling / inability to swallow saliva → indicates potential airway compromise.

2. Neck stiffness / torticollis → suggests posterior pharyngeal involvement (e.g., retropharyngeal infection or injury).

3. Refusal to speak or eat → severe discomfort, possibly painful swallowing (odynophagia).

4. Acute onset over 2 days → could indicate trauma, foreign body, or infection.

Differential Diagnosis (Top Considerations)

Condition	Key Features Supporting	Notes
Retropharyngeal abscess (RPA)	Drooling, dysphagia, neck stiffness/torticollis, fever (may be mild in young child)	Usually post-infectious, may have respiratory distress; more common 6 months–5 years
Retropharyngeal hematoma / tear (trauma)	Acute dysphagia, drooling, neck pain, limited ROM; history of trauma may be absent	Rare; can be from minor blunt trauma or spontaneous (e.g., during vomiting)
Epiglottitis	Drooling, dysphagia, respiratory distress, muffled voice	Usually rapid onset; look for fever, stridor, tripod posture
Foreign body ingestion	Acute dysphagia, refusal to eat, drooling	May have history of ingestion; sudden onset
Cervical spine infection (osteomyelitis/discitis)	Neck stiffness, refusal to move neck, pain	Usually more subacute; may have low-grade fever
Peritonsillar abscess	Uncommon at 2 years; drooling, fever, muffled voice	Usually older children/adolescents

Most likely in this case: Retropharyngeal tear or abscess, given acute dysphagia, drooling, torticollis, and refusal to swallow. The history of neck movement restriction without trauma is suspicious for retropharyngeal injury or infection.

Investigations

1. Airway assessment:

   • Ensure airway patency immediately. Child may need oxygen or urgent ENT/anesthesia review if airway compromise.

2. Imaging:

   • Lateral neck X-ray → widening of retropharyngeal space (> 5 mm at C2 in children)

   • CT neck with contrast → preferred for abscess or hematoma

   • MRI → if concern for soft tissue infection without radiation exposure

3. Lab tests:

   • CBC, CRP, blood cultures (if infection suspected)

Management Principles

Airway

• First priority: secure airway if signs of obstruction or severe drooling/stridor.

Medical Management

• If infection suspected: IV antibiotics (covering typical RPA organisms: Staph aureus, Strep pyogenes, anaerobes)

• If traumatic tear / hematoma: supportive care; monitor airway; surgical intervention if expanding hematoma

Surgical / ENT Intervention

• Indicated if abscess confirmed, airway compromise, or increasing symptoms

• Needle aspiration or incision and drainage

Supportive

• Pain management

• IV fluids if unable to swallow

• Monitor for respiratory distress

Key Teaching Points

1. Red flag symptoms in toddlers: drooling, refusal to eat, neck stiffness → always consider airway compromise.

2. Retropharyngeal space anatomy: children <5 years are more susceptible due to lymph node chains that regress with age, making them prone to abscess/tear.

3. Torticollis in a febrile child → always investigate deep neck space infections.

4. Early imaging is essential; lateral neck X-ray is quick, CT is diagnostic.

5. Airway-first approach saves lives — never delay for imaging if airway compromised.

If you want, I can draw a schematic diagram showing the retropharyngeal space, tear location, and associated clinical signs in a toddler, which is very helpful for teaching or ward discussions.

Do you want me to make that diagram?
