A rare large biliary cystadenoma caused years of abdominal swelling and elevated CA 19.9 levels. Surgical removal normalized these markers, highlighting the importance of recognizing this hepatic lesion.

Area of Science:

  • Hepatobiliary surgery
  • Surgical oncology
  • Gastroenterology

Background:

  • Biliary cystadenomas are rare cystic neoplasms of the liver, typically occurring in middle-aged women.
  • They can present with vague abdominal symptoms or as an incidental finding.
  • Elevated carbohydrate antigen 19.9 (CA 19.9) is a known, though nonspecific, tumor marker associated with these lesions.

Observation:

  • A case of a massive biliary cystadenoma extensively involving the entire peritoneal cavity is presented.
  • The patient experienced prolonged abdominal swelling as the primary manifestation.
  • Preoperative serum analysis revealed significantly elevated levels of carbohydrate antigen 19.9 (CA 19.9).

Findings:

  • Complete surgical excision of the large biliary cystadenoma was successfully performed.

Related Experiment Videos

  • Postoperative follow-up demonstrated a normalization of previously elevated serum CA 19.9 levels.
  • Histopathological examination confirmed the diagnosis of biliary cystadenoma.

    • Implications:

    • This case underscores the potential for biliary cystadenomas to grow to an enormous size, mimicking other intra-abdominal pathologies.
    • Prompt surgical intervention is crucial for both diagnosis and treatment, leading to favorable outcomes.
    • Monitoring CA 19.9 levels can be valuable in managing biliary cystadenomas, with normalization post-surgery indicating successful treatment.
