Summary

Choledochocele, a rare bile duct cyst, was diagnosed in a 63-year-old woman using CT cholangiography. This case is the first to clearly show a choledochocele on transabdominal sonography.

Area of Science:

  • Gastroenterology and Hepatology
  • Medical Imaging
  • Surgical Pathology

Background:

  • Choledochocele represents the rarest subtype of choledochal cysts, posing diagnostic challenges.
  • Bile duct cysts require accurate imaging for timely diagnosis and management.

Observation:

  • A 63-year-old female patient presented with symptoms necessitating bile duct evaluation.
  • Initial conventional sonography did not identify the choledochocele.
  • A subsequent, more detailed transabdominal sonography examination revealed the cystic lesion.

Findings:

  • CT cholangiography confirmed the diagnosis of choledochocele.
  • The detailed transabdominal sonography unambiguously demonstrated the choledochocele.
  • This represents a significant advancement in non-invasive imaging of this rare condition.

Implications:

  • Transabdominal sonography can be a valuable tool for diagnosing choledochocele when performed with high detail.
  • This finding may encourage wider use of detailed sonography in evaluating suspected bile duct anomalies.
  • Improved diagnostic accuracy for choledochocele can lead to earlier intervention and better patient outcomes.
