Does a cystic hygroma mean retardation for the baby if it is born>?

No direct associatn: Ch can occur with kids who have learning or other problems, but it most often occurs as an isolated malformation. Common to the neck region, it can occur as a single or multiple clusters of abnormal lymph vessels. Similar to jumbles of spaghetti these clusters form cysts of varying sizes.Most are present at birth but may enlarge. Surgical removal is curative.This is not assoc with turner syndrome.

Not necessarily: Cystic hygroma is a congenital condition that can have a wide range of consequences. These are mainly anatomic and can be mild to severe. Can be surgically resolved but they can be severe and require significant intervention and may recur later. It can be associated with other syndromes that have more significant problems ie. Turners syndrome but not necessarily. Genetic counseling is recommended.

Usually no: Cystic hygroma is a developmental abnormality of the lymphatic system and per se not a cause of mental retardation.
