[edit] Discussion

  • A cystic hygroma is a localized, single or multiloculated, fluid-filled cavity that usually occurs in the neck.
  • It is believed to develop secondary to congenital blockage of the lymphatic drainage.
  • Cystic hygromas are seen in over one-third of fetuses with nonimmune fetal hydrops.
  • Cystic hygromas have a high association with Turner's syndrome and trisomy syndromes 13, 18, and 21.
