Overview

The diagnosis of peritonsillar abscess may be made without the use of imaging however, imaging options may help in differentiating peritonsillar abscess from other simialr conditions example, peritonsillar cellulitis, retropharyngeal abscess and epiglottitis. On ultrasound [1]peritonsillar abscess appears as focal irregularly marginated hypoechoic area.[2][3][4][1]

Ultrasound

The diagnosis of peritonsillar abscess may be made without the use of imaging however, imaging options may help in differentiating peritonsillar abscess from other simialr conditions example, peritonsillar cellulitis, retropharyngeal abscess and epiglottitis.

This is helpful in differentiating peritonsillar abscess from peritonsillar cellulitis as well as a guide during abscess drainage. The approach may be intraoral or submandibular.[5][2][6][7][8]

On ultrasound the following may be found:[4][1][2][3][4][1]

  • Peritonsillar abscess appears as focal irregularly marginated hypoechoic area.
  • Irregular hypoechoic areas within the tonsil may represent pockets of developing purulence or necrosis called intratonsillar abscesses.
  • Peritonsillar cellulitis appears as enlarged tonsil with ill-defined margins and markedly increased echogenicity of surrounding soft tissues that suggests significant inflammatory change/cellulitis.
