Learning objectives Review and recall the etiologies of cholangitis.Highlight the differential diagnostic criteria at imaging for these entities.Focus on imaging and follow-up of primary sclerosing cholangitis using a standard report.
Read more Background Cholangitis is inflammation of the bile ducts, classified as chronic if it lasts over 6 months. Initial assessment includes medical history, clinical examination, and biological tests. Ultrasound is the first-line imaging for hepatic colic, while cross-sectional imaging is preferred for non-specific symptoms. Cholangiopancreato-Magnetic Resonance Imaging (CP-MRI) is the best option for detailed bile duct exploration.We conducted a retrospective study within our imaging department, known for its subspecialization in digestive pathology, over  one-yearfrom January 2023 to February 2024. A total of...
Read more Findings and procedure details Out of 50 MRI cases analyzed, 35 were diagnosed with primary sclerosing cholangitis (PSC). Cholangitis, a condition marked by inflammation of the bile ducts, has a variety of potential etiologies, including obstructive, infectious [fig 1] , immunological, and other less common causes. The most frequently observed causes are infectious in nature, with secondary sclerosing cholangitis of iatrogenic origin, IgG4-related cholangitis, primary sclerosing cholangitis (PSC), and primary biliary cholangitis (PBC) being the leading diagnoses. Understanding the limitations of MRI and using a structured diagnostic approach...
Read more Conclusion Cholangitis is an inflammation of the biliary tree with various causes.Diagnosis relies on a combination of clinical, biological, and radiological findings.Proficiency in MRCP technique and systematic analysis are essential for accurate diagnosis and effective monitoring.
