Primary pancreatic tumors in children are rare with an overall age-adjusted incidence of 0.018 new cases per 100,000 pediatric patients. The most prevalent histologic type is the solid pseudopapillary neoplasm, followed by pancreatoblastoma. This paper describes relevant imaging modalities and presents consensus-based recommendations for imaging at diagnosis and follow-up.

Shet, MD†,‡ 1. *Children’s Hospital Los Angeles, Los Angeles, CA 2. †George Washington University School of Medicine, Washington, DC 3. ‡Children’s National Hospital, Washington, DC A 10-month-old previously healthy girl presents to the emergency department with new-onset fevers and progressive right forearm swelling, pain, and irritability after a diagnosis of a distal forearm fracture in the same arm 2 weeks earlier. Per the parents’ report, they initially sought care 2 weeks earlier when the child refused to bear weight with the right arm while crawling without any known history of trauma. Outside imaging was reported to be notable for nondisplaced distal radial and ulnar fractures, for which the patient was splinted. Although the family denied a history of trauma, due to the unclear etiology of the fractures, an evaluation for possible nonaccidental trauma was performed that was unrevealing, except for the noted radius and ulna fractures. Follow-up 1 week later had revealed a swollen forearm with repeated plain radiographs that demonstrated abundant periosteal reaction along the distal radius and ulna, presumably representing evidence of healing nondisplaced fractures given the duration since the initial injury (Fig 1). The arm remained swollen but compressible and nontender on examination. Due to the fever, as well as continued swelling of the right distal arm with decreased mobility and worsening pain and irritability, the parents present to …

Osteochondral lesions are common in children and may arise from a variety of etiologies. Although they most frequently occur in the knee, other joints may be involved including the ankle and elbow. We describe the typical imaging appearance of osteochondral lesions with a focus on radiographs and magnetic resonance imaging. Assessment of the stability of these lesions is of paramount importance in directing management. As such, we describe staging schemes as well as imaging features differentiating stable from unstable lesions. Finally, we briefly discuss management strategies as they correlate to imaging findings.

Developmental dysplasia of the hip (DDH) is the most common hip pathology in infants. Although its exact pathophysiology remains incompletely understood, its long-term prognosis depends not only on the severity of the dysphasia, but also on the timely implementation of appropriate treatment. Unrecognized and untreated hip subluxations and dislocations inevitably lead to early joint degeneration while overtreatment can produce iatrogenic complications, including avascular necrosis of the femoral head. In the past two decades, imaging has become an integral part of the clinical screening, diagnosis, and monitoring of children with DDH. Optimal timing for imaging and appropriate use of imaging can reduce the incidence of late diagnoses and prevent iatrogenic complications. In general, ultrasound of the hips is recommended in infants under the age of 4 months while pelvic radiography is recommended in older infants due to the fact that the femoral head ossific nucleus typically is not formed until 4 to 6 months of age. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Objective The aim of the study is to demonstrate the scout radiograph does not change patient management, alter planning, or contribute to interpretation of the outpatient pediatric upper gastrointestinal fluoroscopic examination (UGI). Methods We retrospectively reviewed 197 outpatient pediatric UGIs performed over a 2-year period. We performed a chart review on all patients to evaluate for potentially clinically significant findings on the scout radiograph. Scout findings were categorized into 4 groups: no new clinically significant findings (group 1), potentially clinically significant findings that were not directly addressed in the electronic medical record (group 2), incidental non-gastrointestinal (GI) findings that necessitated further workup, however, were later deemed insignificant (group 3), and clinically significant findings that changed patient GI management, altered the planning of the procedure, or contributed to the interpretation of the fluoroscopic study (group 4). Results A total of 197 UGIs were analyzed. A significant majority of cases (97.0%) were classified into group 1. Three cases (1.5%) were classified into group 2 with findings not addressed in the medical record. Two cases (1.0%) were classified into group 3, which, after further workup, were deemed not clinically significant. One case (0.5%) was classified into group 4, which resulted in a change in patient GI management. Conclusions In our review, there was only 1 case in which the scout radiograph changed patient GI management, with moderate stool burden leading to a miralax cleanout, although there were no cases, which altered the planning of the procedure or contributed to the interpretation of the study. The scout radiograph can be omitted and/or substituted with the last image hold function to decrease radiation exposure.

The University of Maryland Medical Center's goal was to improve the safety and comfort of pediatric imaging by enhancing the experience for children. Two pediatric radiologists and two child life specialists worked together to create a training program to help guide radiology technologists on how to approach and interact with children undergoing medical imaging. The results of surveys administered to technologists and parents or caregivers helped refine the strategy for both creating training sessions for technologists and reading materials for children and their parents to optimally prepare for the procedures. Training sessions included information on language choices, developmental considerations, comfort techniques, patient- and family-centered care practices, procedural support techniques, and coping styles. Through the implementation of learning sessions and distraction resources for technologists, and the development of preparation books, the imaging experience for pediatric patients at UMMC has improved.
