The practice of performing dedicated breast ultrasounds in the pediatric emergency department varies according to institution. In the adult population, breast ultrasounds are commonly interpreted by dedicated breast imagers and/or radiologists appropriately qualified to interpret mammograms. Children's hospitals with dedicated pediatric radiology faculty are less likely to have such individuals on staff. This paper examines the practice of breast ultrasounds ordered in the emergency department throughout a large children's health system. Read More

A four-year-old girl was referred to our service to investigate a mass in her left forearm. About a year before she had cellulitis in the same place which was treated and resolved with antibiotics. A month previous to our consult she notices a soft tissue swelling in her left forearm and a pediatrician referred her to an oncologist for investigation.
On physical examination, she presented with a medial bulging in her left forearm with local pain and no inflammatory signs. There was no history of fever.
The plain radiograph showed a lytic lesion oriented along the axis of the ulna surrounded by fading sclerosis. In the Computed Tomography there was a lytic lesion with periosteal new bone formation.
The diagnosis was Brodie’s abscess which is a form of subacute osteomyelitis. It is a collection of purulent material surrounded by granulation tissue and reparative sclerotic bone. Staphylococcal Aureus is the most common organism to lead to this entity but any pyogenic organism can cause it. Osteomyelitis is the result of bone infection being the trabecular and cortical involved. It can be spread by exogenous and contiguous or endogenous due to hematogenous spread. Read More

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

Postoperative abscess is the most common complication of perforated appendicitis in children with an incidence of 3-25%. Though the imaging algorithms for diagnosis of pediatric appendicitis have evolved to magnetic resonance imaging (MRI), the use of MRI for post-operative evaluation of these children remains in its infancy.
The purpose of our study was to evaluate our experience with a rapid non-contrast MR protocol for evaluation of post-appendectomy cases with concern for abscess. Read More

Development of complications in patients treated for acute appendicitis is not rare. Some authors have advocated the important role of CT in this clinical setting. Increased awareness of radiation-related safety issues in the past years has brought focus on the role and safety of ultrasound (US) to diagnose acute appendicitis in children. However, no study has specifically addressed the role of US for assessment of complications in children operated for acute appendicitis. Our purpose is to evaluate if US is an accurate and safe imaging modality in this setting. Read More

Tubo-ovarian abscesses are uncommon and are usually associated with pelvic inflammatory disease secondary to sexually transmitted disease; however, there has been a small number of reported cases occurring in non-sexually active girls. A series of six virginal girls with tubo-ovarian abscesses is presented for discussion of the clinical circumstances, imaging findings and diagnostic difficulties encountered in this uncommon diagnosis.

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.
