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.

Understanding normal parameters of pediatric cervical spine is imperative for early detection of cervical spine injury by computed tomography (CT) post trauma. Young children have a higher biomechanical fulcrum, incomplete ossification, and increased soft tissue laxity which minimizes anatomical distortion on CT [1,2]. The first part of this two part study aims to establish normal cervical joint spaces measurements in non-traumatic pediatric population with particular attention to the lateral atlantodental interval (ADI).
