Peritonsillar abscess (PTA) is a common and potentially life-threatening infection in the pediatric population. Contrast enhanced computed tomography (CE-CT) has traditionally been used to assist in diagnosis of PTA. However, factors such as radiation exposure, contrast administration and cost have led to increasing interest in the use of ultrasonography for PTA evaluation. The objective of this study was to evaluate the agreement between ultrasound and CE-CT in diagnosing PTA. Read More

Utility of transoral and transcutaneous ultrasound in the evaluation of acute tonsillar inflammation.

Final Pr. ID: Poster #: EDU-059
Peritonsillar abscess (PTA), as a consequence of acute tonsillitis is a very commonly encountered deep infection of the head and neck. Diagnosis of PTA and differentiation from uncomplicated cellulitis based on clinical findings has been shown to be very unreliable. Therefore, imaging diagnosis is a key step in management given the possible need for drainage, in addition to antibiotic therapy. Due to the widespread availability of real-time US, high resolution imaging of the tonsillar and peritonsillar tissue and confident diagnosis of PTA via an intraoral approach is feasible, with literature reporting sensitivities of 90-100%. This offers a valuable diagnostic alternative to the high radiation dose and expense of contrast enhanced CT in the pediatric population. The aim of this exhibit is to review sonographic technique, as well as the normal and pathologic appearance of the palatine tonsils via both transoral and transcutaneous approaches illustrated by a case series obtained at our institution.
