Living with Cysticercosis

An infection from pork tapeworm eggs that form cysts, sometimes in the brain, eyes, heart, or spine.

Understanding Cysticercosis

Cysticercosis is an infection caused by the pork tapeworm, Taenia solium.

It develops when tapeworm eggs from contaminated food enter the body and form cysts. In most cases the worms stay in the muscles and cause no symptoms. Symptoms may occur when the infection is in the brain, eyes, heart, or spine. It is rare in the United States but common in many developing countries.

Signs & symptoms

Symptoms depend on where the cysts are. GARD lists these among the most common:

  • Seizures
  • Calcium deposits in the brain
  • Fluid-filled cysts in the brain or spinal cord area
  • Problems with movement
  • Changes in feeling or sensation
  • Changes in the shape of the brain or its coverings

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.
