Airway Triage & Red-Flag Screening
Before anything, screen for airway compromise and rapidly progressive disease; stabilise the airway (PICU/NICU, ENT, urgent imaging) before working up the mass
The first question in every paediatric neck mass is not what it is but whether the airway is safe. The child is evaluated immediately for airway compromise — stridor, respiratory distress, stertor, drooling, dysphagia, feeding difficulty, voice change, cyanosis and apnoea — and for rapidly progressive disease — a rapidly enlarging neck swelling, deep neck infection, a suspected abscess, a bulky neonatal cervical mass, or mediastinal extension. The neonate with a large cervical teratoma or lymphatic malformation, and the child with a deep neck abscess, are the archetypal airway emergencies.
Where airway compromise is present, management is stabilisation before diagnosis: airway stabilisation, PICU or NICU admission, ENT consultation, urgent ultrasound with CT or MRI as needed, and definitive treatment of the cause. Only where the airway is safe does the structured diagnostic evaluation proceed. This airway-first rule is the organising principle of the whole algorithm — a neck mass that threatens the airway is resuscitated and secured first, and the otherwise-orderly work-up of age, history, examination and imaging is deferred until the child can breathe safely.
- Airway compromise — stridor, respiratory distress, stertor, drooling, dysphagia, feeding difficulty, voice change, cyanosis, apnoea
- Rapidly progressive — rapidly enlarging mass, deep neck infection, suspected abscess, bulky neonatal mass, mediastinal extension
- Airway compromise → airway stabilisation, PICU/NICU, ENT consult, urgent US ± CT/MRI, definitive treatment
- Airway safe → proceed to the structured diagnostic evaluation
★ High-yield pearls (chapter-wide)
- Airway compromise comes before diagnosis — stridor, respiratory distress, drooling or a rapidly enlarging neonatal mass is stabilised first (airway, PICU/NICU, ENT, urgent imaging) before any work-up of the mass itself.
- Age is the most powerful diagnostic filter — the neonatal mass (teratoma, lymphatic malformation, haemangioma) differs fundamentally from the child's (reactive nodes, thyroglossal cyst, mycobacteria) and the adolescent's (thyroid disease, lymphoma).
- Duration narrows the differential — acute (<2 weeks) suggests viral or bacterial lymphadenitis, subacute (2–6 weeks) cat-scratch or atypical mycobacteria, and chronic (>6 weeks) a congenital lesion, tuberculosis or a neoplasm.
- The constitutional red flags — fever, weight loss, night sweats, hepatosplenomegaly, a supraclavicular node, or a mass persisting beyond six weeks — trigger an immediate malignancy work-up, not further observation.
- Midline versus lateral location reframes the differential — a midline mass is a thyroglossal cyst, dermoid, ectopic thyroid, teratoma or ranula; a lateral mass is reactive nodes, a branchial anomaly, a lymphatic malformation, a haemangioma, a thymic cyst or a neoplasm.
- Ultrasound is the first imaging study in almost every paediatric neck mass — it distinguishes solid from cystic, assesses vascularity and the thyroid, and identifies an abscess, all without sedation or radiation.
- Confirm a normal thyroid gland before excising a midline thyroglossal cyst — the cyst may contain the only functioning thyroid tissue, and the definitive operation is the Sistrunk procedure, not simple cystectomy.
- Oral propranolol is first-line for the complicated infantile haemangioma — airway, feeding, visual or cardiac compromise, or ulceration — with monitoring for bradycardia, hypotension and hypoglycaemia; most uncomplicated haemangiomas simply involute.
- A unilateral node with violaceous skin and a draining sinus is non-tuberculous mycobacterial disease until proven otherwise, and surgical excision — not prolonged antibiotics — is the preferred treatment.
- The complex paediatric neck mass is a multidisciplinary problem — ENT, paediatric surgery, radiology, pathology, oncology, genetics, infectious disease and interventional radiology — and the syndromic associations (BOR, CHARGE, Turner, Noonan) warrant a genetics referral.

Decision tree
Airway safety comes before diagnosis. The stable child is filtered by age and location, characterised by ultrasound, and given a tissue diagnosis by FNAC or biopsy — routing to one of eleven aetiology-keyed pathways across congenital, infective, vascular, syndromic and neoplastic disease.
