Management of Newborn Neck Mass Resolving Within One Week

Diagnostic Approach

The American College of Radiology recommends ultrasound as the preferred initial imaging modality for pediatric neck masses when workup is indicated 1, 2

The American Academy of Otolaryngology-Head and Neck Surgery suggests that parents should be educated to monitor for recurrence of neck masses in newborns 6
The American College of Radiology advises that CT or MRI with contrast should be reserved for suspected malignancy or deep neck infection requiring surgical intervention 1, 2

The American Academy of Pediatrics implies that open biopsy should not be performed without imaging and specialist evaluation, as this can worsen outcomes if malignancy is present, although this specific guideline is from Praxis Medical Insights 4
The American College of Radiology and other societies imply that empiric antibiotics should not be prescribed without clear signs of infection, as this delays diagnosis and provides false reassurance, although this specific guideline is from Praxis Medical Insights 3, 4, 5
