Ascaris lumbricoides infestation can cause biliary lithiasis (gallstones) in young adults. This case highlights the importance of considering parasitic infections in gallstone disease diagnosis.

Area of Science:

  • Hepatology
  • Parasitology
  • Gastroenterology

Background:

  • Biliary lithiasis, or gallstone formation, is a common condition often associated with cholesterol or bilirubin stones.
  • Ascaris lumbricoides, a common intestinal nematode, can migrate to the biliary tract, leading to parasitic gallstones.

Observation:

  • A young male patient presented with symptoms indicative of biliary lithiasis.
  • Diagnostic investigations revealed gallstones directly linked to an Ascaris lumbricoides infestation within the biliary system.

Findings:

  • The case demonstrates a rare etiology of biliary lithiasis, specifically parasitic gallstones caused by Ascaris lumbricoides.
  • Pathogenesis involves adult worms or their eggs obstructing or irritating the biliary tract, promoting stone formation.

Implications:

  • This case underscores the need to include parasitic infections in the differential diagnosis of biliary lithiasis, particularly in endemic areas.
  • Understanding the clinical features and pathogenesis can improve diagnostic accuracy and patient management for this unusual cause of gallstones.
