case_images: At 23+ weeks of gestation, the size of 7.2x6.5x6.3 cm septate cystic mass was found on the right side of the neck of the fetus by ultrasonography, which was considered to be LM of the fetal neck (Figure 1A). During gestation, the septate cystic mass gradually increased in size, with no fetal hydrops (Figure 1B and C).

case_images: The umbilical cord was extremely twisted in 53 laps, and there was a cystic mass (10x16x8 cm) on the right side of his neck (Figure 3A). At 3 days of age, due to progressive growth of the mass secondary to intralesional bleeding (Figure 3B), the neonate was treated by cervical sclerotherapy with bleomycin 1500 U. One year after his birth, the mass had disappeared (Figure 3C).
