Persistent common bile duct hematoma caused by a small cancer: case report

Area of Science:

• Gastroenterology and Hepatology
• Diagnostic Imaging
• Surgical Oncology

Background:

• Intrabiliary duct hematomas are rare complications.
• Choledochal cancers can present with varied imaging findings.
• Accurate preoperative diagnosis is crucial for effective treatment planning.

Observation:

• A case of intrabiliary duct hematoma secondary to choledochal cancer is presented.
• The hematoma was observed for over one month.
• Initial noncontrast enhanced computed tomography (CT) revealed a high-attenuation mass.

Findings:

• The high-attenuation mass on CT mimicked a choledochal stone or calcified tumor.
• The underlying cause was an intrabiliary hematoma associated with a smaller choledochal cancer.
• Delayed or misdiagnosis can impact patient outcomes.

Implications:

• This case highlights the importance of considering hematoma in the differential diagnosis of biliary tract masses.
• Advanced imaging techniques may be necessary for definitive diagnosis.
• Early and accurate diagnosis of choledochal cancer is vital for timely intervention and improved prognosis.
