Quinn NA, et al. - Authors reviewed the evaluation of children with a deep lateral neck infection and defined the effect of initial imaging modality on outcomes and costs. Findings suggested no impact of the primary imaging modality (ultrasound or computed tomography) used to work-up children with a lateral neck infection on the length of stay or hospital cost. Nonetheless, a coexisting retropharyngeal infection was seen in a significant subset that was only identified on computed tomography.
