Department of Radiology, Case Western Reserve University, Cleveland, OH, USA.

Sclerosing cholangitis is a chronic cholestatic disease characterized by stricturing, beading, and obliterative fibrosis of the bile ducts. Sclerosing cholangitis is considered primary (PSC) if no underlying etiology is identified or secondary (SSC) if related to another identifiable cause. In this article, we will review the clinical features, pathogenesis, diagnosis, and imaging findings of PSC and SSC, with an emphasis on features that may aid in the distinction of these entities.

Mimics of cholangiocarcinoma: spectrum of disease.

Radiographics 2008 Jul-Aug;28(4):1115-29

Department of Radiology, Mallinckrodt Institute of Radiology, St Louis, MO, USA.

Cholangiocarcinoma is the second most common primary malignant hepatobiliary neoplasm, accounting for approximately 15% of liver cancers. Diagnosis of cholangiocarcinoma is challenging and the prognosis is uniformly poor, with recurrence rates of 60%-90% after surgical resection. A wide spectrum of neoplastic and nonneoplastic conditions of the biliary tract may masquerade as cholangiocarcinoma, adding to the complexity of management in patients suspected to have cholangiocarcinoma.

Parasitic infestations of the biliary tract.

Curr Gastroenterol Rep 2007 Apr;9(2):156-64

Department of Gastroenterology, Post Graduate Institute of Medical Education and Research, 1041, Sector 24-B, Chandigarh 160 023, India.

Parasitic infestations of the biliary tract are a common cause of biliary obstruction in tropical countries and can lead to such serious complications as cholangitis and cholangiocarcinoma. Endoscopic therapy has helped in the management of biliary complications caused by these parasites. Ascaris lumbricoides organisms, which normally reside in the jejunum, are actively motile and can invade the papilla, thus migrating into the bile duct and causing biliary obstruction. Read More

Unusual cases of acute cholecystitis and cholangitis: Tokyo Guidelines.

J Hepatobiliary Pancreat Surg 2007 30;14(1):98-113. Epub 2007 Jan 30.

Department of Surgery, Teikyo University Chiba Medical Center, 3426-3 Anesaki, Ichihara, Chiba, 299-0111, Japan.

Unusual cases of acute cholecystitis and cholangitis include (1) pediatric biliary tract infections, (2) geriatric biliary tract infections, (3) acalculous cholecystitis, (4) acute and intrahepatic cholangitis accompanying hepatolithiasis (5) acute biliary tract infection accompanying malignant pancreatic-biliary tumor, (6) postoperative biliary tract infection, (7) acute biliary tract infection accompanying congenital biliary dilatation and pancreaticobiliary maljunction, and (8) primary sclerosing cholangitis. Pediatric biliary tract infection is characterized by great differences in causes from those of adult acute biliary tract infection, and severe cases should be immediately referred to a specialist pediatric surgical unit. Because biliary tract infection in elderly patients, who often have serious systemic conditions and complications, is likely to progress to a serious form, early surgery or biliary drainage is necessary.

From the RSNA refresher courses: imaging evaluation for acute pain in the right upper quadrant.

Radiographics 2004 Jul-Aug;24(4):1117-35

Department of Medical Imaging, University Health Network and Mount Sinai Hospital, University of Toronto, Ontario, Canada.

Acute cholecystitis is the most common cause of acute pain in the right upper quadrant (RUQ), and urgent surgical removal of the gallbladder is the treatment of choice for uncomplicated disease. However, cross-sectional imaging is essential because more than one-third of patients with acute RUQ pain do not have acute cholecystitis. In addition, patients with complications of acute cholecystitis, such as perforation, are often best treated with supportive measures initially and elective cholecystectomy at a later date.
