A cystic hygroma is a mass that commonly occurs in the head and neck area. It is a birth defect.
Alternative NamesLymphangioma
Causes, incidence, and risk factorsA cystic hygroma occurs as the baby grows in the womb. It forms from pieces of material that carry fluid and white blood cells. Such material is called embryonic lymphatic tissue. After birth, a cystic hygroma usually looks like a soft bulge under the skin. The cyst may not be recognized at birth. It typically grows as the child does, and sometimes is not noticed until the child is older.
Sometimes, a cystic hygroma is seen when the baby is still in the womb using a pregnancy ultrasound. This can mean that the baby has a chromosomal problem or other birth defects.
SymptomsA common symptom is a neck mass found at birth, or discovered later in an infant after an upper respiratory tract infection.
Signs and testsThe following tests may be done:
- Chest x-ray
- Ultrasound
- CT scan
If the cystic hygroma is detected during a pregnancy ultrasound, other ultrasound tests or amniocentesis may be recommended.
TreatmentTreatment involves complete removal of the abnormal tissue whenever possible. However, cystic hygromas can often invade other neck structures, making this impossible.
Other treatments have been attempted with only limited success. These include:
- Chemotherapy medications
- Injection of sclerosing medications
- Radiation therapy
- Steroids
The outlook is good if surgery can totally remove the abnormal tissue. In cases where complete removal is not possible, the cystic hygroma commonly returns.
The outcome may also depend on what other chromosomal abnormalities or birth defects, if any, are present.
ComplicationsComplications may include:
- Bleeding
- Damage to structures in the neck caused by surgery
- Infection
- Return of the cystic hygroma
If you notice a lump in your neck or your child's neck, call your doctor.

What causes cystic hygroma?
Cystic hygroma is caused by a developmental defect in the lymphatic system, leading to the formation of fluid-filled sacs or cysts, typically in the neck or head region. This condition often arises during fetal development when lymphatic vessels fail to form properly. While the exact reasons for this abnormality are not fully understood, it may be associated with genetic factors or chromosomal abnormalities. Cystic hygromas can be detected through prenatal imaging techniques such as ultrasound.
What is the cpt code for excision of congenital cystic hygroma with dissection of deep neurovacularity?
The CPT code for the excision of a congenital cystic hygroma with dissection of deep neurovascular structures is typically 21555. This code is used for the excision of a tumor or cyst in the neck or face region, which includes the necessary dissection of surrounding neurovascular structures. However, it is always advisable to consult the most recent CPT coding guidelines or a coding specialist to ensure accuracy and compliance.
When is the diagnosis of cystic hygroma possible I had an ultrasound done at 8w5d and they said there is increased fluid around the baby's neck but did not give a diagnosis.?
Normally diagnosed between 9 and 16 weeks' gestation.
What is a cystic foci in a kidney?
A cystic foci, or cystic focus, is when an ultrasound identifies a finding that is cystic-like. It mean there's a tiny collection of fluid wherever the cystic focus was found.
