Living with Alveolar echinococcosis

A rare parasitic infection from swallowing Echinococcus multilocularis eggs, which affects the liver after many symptom-free years.

Understanding Alveolar echinococcosis

Alveolar echinococcosis is a rare parasitic disorder that happens after swallowing eggs of a parasite called Echinococcus multilocularis.

There is first a long period with no symptoms, which can last many years. After that, it follows a long-lasting course with belly pain and jaundice. GARD lists the onset as adulthood and older adulthood.

Signs & symptoms

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

  • Belly pain
  • Yellowing of the skin and eyes (jaundice)
  • Tiredness (fatigue)
  • Fever
  • Swelling in the feet and ankles
  • Reduced liver function

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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