Figure 2. A 58 year-old man with long lasting primary sclerosing cholangitis and ulcerative cholangitis. A stenosis in the hepatic duct associated with focal bile duct thickening with enhancement at MRI was detected. A diagnostic ERCP was performed, confirming the presence of a noncritical stenosis of 2.5 mm in diameter and 5 mm in length in the hepatic duct, just below the hepatic confluent. Brush cytology and biopsy were obtained for anatomopathological analysis, and no atypia were found.
