Chemotherapy-induced sclerosing cholangitis (CISC) presents with biliary dilatation and strictures primarily affecting the hepatic porta. Imaging may reveal perfusion abnormalities and metastatic disease, differing from primary sclerosing cholangitis.

Area of Science:

  • Radiology
  • Gastroenterology
  • Oncology

Background:

  • Chemotherapy-induced sclerosing cholangitis (CISC) is a rare but serious complication.
  • Understanding its imaging features is crucial for diagnosis and management.

Purpose of the Study:

  • To review and characterize the computed tomography (CT), magnetic resonance imaging (MRI), and cholangiographic findings of CISC.

Main Methods:

  • Retrospective review of 11 patients with CISC identified from an endoscopic retrograde cholangiography database (1995-2004).
  • Analysis of 12 CT, 4 MRI, 69 endoscopic, and 9 antegrade cholangiographic studies.
  • Assessment of serial changes and response to endoscopic treatment.

Main Results:

  • CISC demonstrated segmental irregular biliary dilatation and strictures in proximal extrahepatic bile ducts, sparing the distal common bile duct.

  • CT/MRI revealed altered liver perfusion, metastases, or peritoneal carcinomatosis.
  • Ten patients required repeated stenting for biliary strictures (mean interval: 4.7 months).

    • Conclusions:

    • CISC shares cholangiographic similarities with primary sclerosing cholangitis (PSC) but predominantly affects ducts at the hepatic porta.
    • Multiphasic contrast-enhanced CT or MRI can identify perfusion abnormalities, liver lesions, or metastatic disease in CISC.
