This study reports on three sisters diagnosed with Caroli's disease, a rare condition causing bile duct dilatation. While symptoms varied, the findings highlight the importance of family screening for this genetic disorder.

Area of Science:

  • Hepatology
  • Medical Genetics

Background:

  • Caroli's disease, characterized by cystic dilatation of intrahepatic bile ducts, is a rare congenital condition.
  • Its exact mode of inheritance is debated, though often considered autosomal recessive.

Observation:

  • Three sisters presented with varying clinical manifestations of Caroli's disease.
  • The index case exhibited symptoms including fever, abdominal pain, hepatic lithiasis, and cholangitis.
  • Two asymptomatic older sisters were also diagnosed, indicating variable penetrance and expressivity.

Findings:

  • Diagnostic imaging modalities like ultrasonography, CT, and ERCP confirmed Caroli's disease.
  • Analysis of 13 families suggests a complex hereditary pattern, with individual symptom presentation and disease progression differing significantly.

  • The study could not definitively establish the mode of transmission due to limited parental data.

    • Implications:

    • Highlights the need for comprehensive family evaluations in suspected Caroli's disease cases.
    • Suggests potential genetic heterogeneity or complex inheritance patterns beyond simple autosomal recessive transmission.
    • Emphasizes the importance of early diagnosis and management to prevent complications such as cholangitis and lithiasis.
