Living with Caroli disease

A condition in which bile ducts in the liver are widened, along with kidney cysts, causing repeated liver problems.

Understanding Caroli disease

Caroli disease is a condition in which the bile ducts inside the liver (the tubes that carry bile) are abnormally widened, along with cysts in the kidneys.

People with this condition can have repeated episodes of slowed bile flow (cholestasis), stones in the bile ducts, and bacterial infection of the bile ducts (cholangitis). In Caroli syndrome, liver scarring (fibrosis) and high blood pressure in the portal vein (portal hypertension) may also occur.

Signs & symptoms

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

  • Belly pain
  • Yellowing of the skin and eyes (jaundice)
  • Bile duct infection (cholangitis)
  • Slowed or blocked flow of bile (cholestasis)

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 digestive system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in PKHD1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

Quick facts

InheritanceAutosomal Recessive
GenesPKHD1

Changes in the PKHD1 gene are linked to this condition. It is inherited in an autosomal recessive way, so a child inherits a changed copy of the gene from each parent. GARD says the underlying cause is poorly understood.
