AN ANTENATAL ultrasound examination of a 39-year-old woman with a pregnancy of 21 weeks' gestation demonstrated a large, complex, multicystic cervical mass measuring 10 × 12 cm on the fetus. The neck mass was felt to be compressing the upper airway and, potentially, the esophagus. The prenatal course was complicated by maternal polyhydramnios. The infant was delivered at term via an EXIT (ex utero intrapartum treatment) procedure. At delivery, a huge mass was noted surrounding the infant's neck (Figure 1). The infant was immediately intubated.
The mass was excised on the third day of life (Figure 2).
