lymphatic system, often in the head and neck area. A cystic hygroma may be discovered in a fetus during a pregnancy ultrasound, present as a birth defect (congenital) in a newborn, or it may not become evident until later in life. The causes include environmental factors, genetic factors, or unknown factors. The majority of prenatally diagnosed cystic hygromas are due to a chromosomal abnormality known as Turner syndrome, in which a female has only one X chromosome instead of two. 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 can occur as an isolated finding or with other birth defect as part of a syndrome. Isolated cystic hygroma may be inherited as an autosomal recessive disorder. A fetal cystic hygroma may progress to hydrops (an excess amount of fluid in the body) and eventually to fetal death. 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. Fetal cystic hygroma may be treated with serial thoracocentesis plus paracentesis.Cystic hygroma (meaning “moist tumor”) are fluid-filled sacs that result from a blockage in the
