Suspicious vs reactive lymph node — criteria?

Reactive: oval, preserved central hilum, hilar vascularity. Suspicious: round (S/L > 0.5), hilum loss, peripheral/chaotic vascularity, microcalcifications, central necrosis.

Cervical cystic lesion — differentials?

Branchial cleft cyst (lateral, 2nd arch — adjacent to SCM), thyroglossal cyst (midline, suprahyoid), cystic hygroma, abscess, lymphangioma. Location + echostructure orient the differential.

Transfontanellar US — useful window?

Until anterior fontanelle closure (typically 12–18 months). After that, MRI is the imaging method in neonatal emergency.

Report template — Ultrasound of skull/brain transfontanellar

When to use

Cervical and soft-tissue US is useful for palpable neck masses, lymphadenopathy, salivary gland disease, superficial skin/subcutaneous lesions and collections. Transfontanellar US is the initial method in neonates for IVH and hydrocephalus.

What to evaluate

Lymph nodes: morphology, central hilum, cortical thickness, Doppler vascularity.
Salivary glands: size, echotexture, stones (sialolithiasis), focal lesions.
Superficial masses: size, composition, involved planes, vascularity.
In neonates (transfontanellar): ventricles, parenchyma, hemorrhage, ischemia.
