Cystic Hygroma
Overview
Cystic hygroma is a birth defect that causes a soft mass, often in the head and neck area. It may be discovered in a fetus during a pregnancy ultrasound, in a newborn, or it may not become evident until later in life. When a cystic hygroma is identified in a fetus, parents are counseled regarding their baby's risk for having a chromosome problem or other birth defect, and are offered additional testing options such as special ultrasound tests or amniocentesis. Cystic hygromas in infants, children, or adults may enlarge or become infected, and may require surgery or other therapy to remove or shrink the mass.
