Follicular cholangitis may lead to severe focal biliary stricture, which is difficult to distinguish from cholangiocarcinoma. This is the report of a rare case of follicular cholangitis associated with an intrahepatic focal biliary stricture in a 69-year-old woman. The patient visited our hospital for upper abdominal pain in 2006. Computed tomography revealed common bile duct stones and focal stricture of the left intrahepatic duct. Endoscopic retrograde cholangiopancreatography revealed a severe B3 stricture and dilation of the peripheral biliary tract. Repeated cytology revealed no malignancy. The patient was followed up for 8 years and repeated attacks of cholangitis severely compromised her quality of life. A left hepatectomy was performed, and the pathological findings were consistent with follicular cholangitis. It is generally difficult to make a definitive diagnosis after identifying a biliary stricture, and the stricture is often treated with surgical resection. The clinical presentation and radiological findings of follicular cholangitis are similar to those of cholangiocarcinoma; therefore, if a conservative approach is selected, frequent follow-up is recommended. The present case suggests that follicular cholangitis should be considered in the differential diagnosis of biliary stricture. [ABSTRACT FROM AUTHOR]
