Living with Congenital pulmonary lymphangiectasia

A rare lung condition present from birth in which lymph vessels in the lungs are too wide, often causing breathing trouble.

Understanding Congenital pulmonary lymphangiectasia

Congenital pulmonary lymphangiectasia (CPL) is a rare lung condition present from birth in which lymph vessels in the lungs are abnormally wide.

Lymph vessels drain fluid from the body and help the immune system. In CPL it often shows up in the first few days of life as breathing failure, sometimes with a bluish skin tint (cyanosis). It can be noticed before birth with fluid buildup (hydrops fetalis) or fluid around the lungs (pleural effusion). CPL can be primary, alone or part of a wider lymph condition, or secondary to heart problems or lymph blockage.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Trouble breathing (respiratory distress)
  • Bluish skin color (cyanosis)
  • Fluid around the lungs (pleural effusion)
  • Cough
  • Fluid in the belly (ascites)
  • Slow growth

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and lung and breathing specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Children's Interstitial Lung Disease Foundation and Lymphatic Education and Research Network may keep lists of experts for this condition.
