To show the role of ultrasound (US) in distinguishing retropharyngeal abscess from adenitis in children. Eleven infants and children had clinical symptoms suggestive of retropharyngeal infection. Radiographic evaluation included, lateral neck radiography (11/11), contrast-enhanced neck CT (10/11), contrast-enhanced neck MR (1/11), and real time US (11/11) patients. US was used to characterize masses as solid (adenitis) or complex (abscess) and for guiding intraoperative aspiration and drainage. Contrast CT and MR showed findings suspicious for abscess in all 11 cases. Only three children had surgically drainable abscesses. CT numbers within inflammatory masses did not distinguish adenitis from abscess. US was able to correctly diagnose abscess or adenitis in each case. Lateral neck radiography and contrast CT identify and localize retropharyngeal inflammatory masses in children. US, but not CT, distinguishes between adenitis and abscess and aids in intraoperative aspiration and drainage.
