AB Key  PointsCystic  hygroma  and  lymphangioma  are  older  commonly  used  terms  for  a  specific  type  of  vascular  malformation.Most  often  seen  in  the  soft  tissue  of  the  neck,  axilla,  thorax,  and  lower  extremities.Different  prenatal  natural  history  if  diagnosed  in  the  first  trimester  versus  the  third.Lymphangiomas  presenting  in  the  third  trimester  usually  seen  in  the  anterior  or  anterolateral  neck  are  not  usually  associated  with  other  anomalies  or  hydrops.Lymphatic  vascular  malformations  consisting  of  cysts  separated  by  fine  septa.While  the  mortality  of  lymphatic  vascular  malformations  prior  to  30  weeks’  gestation  is  high,  due  to  hydrops  and  karyotype  abnormalities,  those  presenting  later  have  an  excellent  prognosis.Cervical  lymphangiomas  are  at  risk  for  airway  compromise,  and  an  EXIT  procedure  should  be  considered  if  there  is  evidence  of  airway  compression  or  displacement.
