Cystic Hygroma (Lymphangioma)

Cystic hygroma is a benign, but potentially serious, congenital birth defect characterized by fluid-filled sacs, typically found in the neck or head area.

These collections of lymphatic fluid can grow and become symptomatic, causing complications that may require specialized treatments.

Cystic hygromas often develop prenatally or shortly after birth. Early detection is crucial for effective treatment.

While benign, cystic hygromas can lead to impairments in breathing, swallowing and appearance, depending on their size and location.

Symptoms

Recognizing the symptoms of cystic hygroma is vital for timely medical intervention. Common symptoms include:

• Soft, fluid-filled masses in the neck or head: These are the primary signs of cystic hygroma, often noticeable as swelling or lumps.
• Respiratory distress or difficulty swallowing: The masses can press against the airways or esophagus, causing breathing or feeding issues.
• Increased size of the masses over time: Cystic hygromas can grow, leading to more pronounced symptoms and potential complications.

Risk factors

Cystic hygroma can affect anyone, but certain factors may increase the likelihood of its development. Understanding these risk factors can help in early detection and management.

Key risk factors associated with cystic hygroma include:

• Genetic conditions such as Turner syndrome: Conditions such as Turner syndrome and Down syndrome are often linked to a higher risk of cystic hygroma.
• Intrauterine infections: Infections during pregnancy can sometimes contribute to the development of cystic hygromas.
• Family history of cystic hygroma: A family history of cystic hygroma or other lymphatic anomalies may increase the likelihood of occurrence.
• Environmental factors: Certain environmental exposures during pregnancy might elevate the risk, though these are less clearly defined.

By being aware of these risk factors, families and health care providers can work together to monitor and manage cystic hygroma effectively, ensuring the best possible outcomes for affected individuals.

Screenings and diagnosis

Prenatal ultrasound screenings often detect cystic hygromas, particularly in the second trimester.

After birth, physical examination, ultrasound and magnetic resonance imaging (MRI) are essential for a thorough diagnosis, helping to detail the location, size, and impact of the hygromas.

Treatment options

Treatment options can include surgery, medication and injections:

• Surgical removal: Larger or symptomatic cystic hygromas often require surgical removal.
• Sclerotherapy: For some types of cystic hygromas, the doctor can inject a fluid into the cyst. This procedure, called sclerotherapy, may be done a few times over a period of weeks, depending on the size of the cyst. Depending on the type of cyst, this treatment can be highly effective.

Potential complications and recovery

Complications after surgery can include infection, bleeding or recurrence of the hygroma.

Postoperative care is integral to recovery. Regular follow-up visits, imaging studies, and physical therapy ensure optimal healing and functional restoration.

Chronic conditions and recurrence

While rare, cystic hygromas can recur (come back). Chronic conditions arising from untreated or large hygromas—that impact breathing or swallowing—are managed through personalized care plans, ensuring patients lead healthy lives.
