Overview

CT scan

  • Imaging is helpful in differentiating peritonsillar abscess from peritonsillar cellulitis as well as a guide during abscess drainage.[1][2][3][4][5]
  • CT scan is helpful in defining the characteristics of the abscess as well as to classify it.
  • It also helps in guiding the possible complications. For example patients with inferior cap-type abscess are at highest incidence of extraperitonsillar spread than the other categories of peritonsillar abscess.[6]
  • Coronal contrast-enhanced CT scan of the neck may identify the peritonsillar abscess[2] however, the use of CT scan is associated with a clinically significant delay in time to an otolaryngology consultation, time to admission, and time to bedside procedure.[7]
  • CT scan may show diffuse hypodense lesion with rim enhancement in the peritonsillar space.[8]
