*Intraoral or submandibular ultrasound distinguish PTA from cellulitis and guide needle aspiration

*Submandibular ultrasound may be superior to intraoral ultrasound when limited by trismus or pain.
*+/- exudates, [[lymphadenopathy]]
*PTA will have echo-free cavity with irregular border
*Peritonsillar cellulitis appears as homogenous area with no fluid collection
* Do not recommend CT to differentiate PTA from cellulitis
**Recommend CT with IV contrast to identify deep space neck infection
*Clinical features may not always distinguish PTA from cellulitis
**24-hour trial of antimicrobial therapy may be helpful
***Response is defined by improvement of sore throat, fever, trismus or alleviation of tonsillar inflammation

Background

Anatomy of the posterior pharynx.
  • Peritonsillar cellulitis- inflammatory reaction between palatine tonsil and pharyngeal muscle with no discrete collection of pus.
  • Peritonsillar abscess - collection of pus located between palatine tonsil and pharyngeal muscle.

Clinical Features

Differential Diagnosis

Acute Sore Throat

Bacterial infections

Viral infections

Noninfectious

Other

Evaluation

  • Imaging may be necessary to differentiate peritonsillar abscess (PTA) from peritonsillar cellulitis, epiglottitis, deep space neck infection
  • Intraoral or submandibular ultrasound distinguish PTA from cellulitis and guide needle aspiration
    • Submandibular ultrasound may be superior to intraoral ultrasound when limited by trismus or pain.
    • PTA will have echo-free cavity with irregular border
    • Peritonsillar cellulitis appears as homogenous area with no fluid collection
  • Do not recommend CT to differentiate PTA from cellulitis
    • Recommend CT with IV contrast to identify deep space neck infection

Management
