Abstract
We present the case of a 32-year-old pregnant woman, G3P2, with no relevant medical history, referred to a tertiary care center due to the prenatal detection of a fetal cervical mass. The initial diagnosis was made at 23 weeks + 5 days of gestation, revealing a large mass located at the lower mandibular region, with mixed components and marked vascularization on color Doppler, associated with significant fetal neck hyperextension. Serial ultrasound follow-up demonstrated progressive growth of the lesion, polyhydramnios, and suspected airway compression. These findings led to delivery planning by cesarean section with an EXIT (Ex Utero Intrapartum Treatment) procedure at 38 weeks of gestation, successfully securing the neonatal airway through orotracheal intubation at birth. In the postnatal period, the newborn was diagnosed with cystic hygroma and acyanotic congenital heart disease, requiring interventional management with serial drainages and bleomycin sclerotherapy, and remaining under mechanical ventilation. This case highlights the importance of prenatal diagnosis, multidisciplinary management, and perinatal planning in fetuses with congenital cervical masses and risk of airway obstruction.
