ABSTRACT
INTRODUCTION: Clinical clearance of a child's cervical spine after trauma is often challenging because of impaired mental status or an unreliable neurologic examination. Magnetic resonance imaging (MRI) is the criterion standard for excluding ligamentous injury in children but is constrained by long image acquisition times and frequent need for anesthesia. Limited-sequence magnetic resonance imaging (LSMRI) is used in evaluating the evolution of traumatic brain injury and may also be useful for cervical spine clearance while potentially avoiding the need for anesthesia. The purpose of this study was to assess the sensitivity and negative predictive value of LSMRI as compared with criterion standard full-sequence MRI as a screening tool to rule out clinically significant ligamentous cervical spine injury. METHODS: We conducted a 10-center, 5-year retrospective cohort study (2017-2021) of all children (0-18 years) with a cervical spine MRI after blunt trauma. Magnetic resonance imaging images were rereviewed by a study pediatric radiologist at each site to determine if the presence of an injury could be identified on limited sequences alone. Unstable cervical spine injury was determined by study neurosurgeon review at each site. RESULTS: We identified 2,663 children younger than 18 years who underwent an MRI of the cervical spine with 1,008 injuries detected on full-sequence studies. The sensitivity and negative predictive value of LSMRI were both >99% for detecting any injury and 100% for detecting any unstable injury. Young children (younger than 5 years) were more likely to be electively intubated or sedated for cervical spine MRI. CONCLUSION: Limited-sequence magnetic resonance imaging is reliably detects clinically significant ligamentous injury in children after blunt trauma. To decrease anesthesia use and minimize MRI time, trauma centers should develop LSMRI screening protocols for children without a reliable neurologic examination. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level III.

There is a wide variety of disease entities in children, which can present with cervical adenopathy. The spectrum of pathology and imaging appearance differs in many cases from that seen in adults. This review aims to compare the strengths and limitations of the various imaging modalities available to image pediatric patients presenting with cervical adenopathy, provide guidance on when to image, and highlight the imaging appearance of both common and uncommon disorders affecting the cervical nodes in children to aid the radiologist in their clinical practice.

Imaging plays an important role in evaluating patients with suspected intrauterine and perinatal infections. Advances in fetal imaging including both ultrasound and MRI allow for increasingly more specific diagnosis if the radiologist is familiar with specific imaging features and patterns. Early imaging of neonates with suspected central nervous system infection is valuable to enable prompt treatment and differentiate infection from other conditions which can clinically present similarly. Ultrasound is a useful initial modality to screen for abnormalities however MRI with and without contrast remains the optimal examination to characterize infection, evaluate for potential surgical targets, and provide prognostic information.

Hairy polyps are benign lesions found in the oropharynx or nasopharynx that are thought to be present at birth and can lead to upper airway obstruction in infants. Also known as naso-oropharyngeal choristoma, they are increasingly viewed as aggregates of bigeminal tissue, likely from the first or second branchial arches, found in aberrant locations. They are benign lesions that are usually successfully treated by surgical excision. Here we present a rare case of a hairy polyp originating in the eustachian tube of a 7-week-old male, discuss our management of the patient, and put forth a new hypothesis as to the origin of these lesions.
