ステップ 1 · Mass nature + airway involvement
Mass nature + airway involvement assessment (fetal MRI)?
💡 Neck masses: lymphatic malformation (cystic hygroma, most common), cervical teratoma (solid + cystic ± calcification), hemangioma, etc. Fetal MRI is better than ultrasound: assesses extent, airway (tracheal/esophageal compression-deviation), soft-tissue characterization (T1 high = hemorrhage/fat; multiseptated cystic = lymphatic), relation to vessels/spine, differentiates goiter.

- Small mass, trachea midline, normal amniotic fluid, no compression → 低リスク · follow up + plan delivery
- Large mass (>5 cm)/anterior/tracheal deviation-compression/polyhydramnios/extension into the mediastinum → Airway involvement → plan EXIT
- 【終点】低リスク · follow up + plan delivery頚部腫瘤で気道閉塞リスク→EXIT適応を検討。多科シミュレーション分娩。
- 【終点】Airway involvement → plan EXITLarge mass (>5 cm)/anterior/tracheal deviation-compression/polyhydramnios (impaired swallowing)/extension into the mediastinum = high airway-involvement risk: plan EXIT (ex-utero intrapartum treatment) — partial deliveryによりcesarean, secure the airway while maintaining placental circulation・oxygenation (laryngoscopy/挿管/bronchoscopy/tracheostomyまたは切除)前にclamping the cord; multidisciplinary (OB/ENT-小児 手術/anesthesia/neonatology/画像検査).
