Abstract

Inflammatory pseudotumors are infrequently occurring lesions, characterized by a localized mass composed of a benign proliferation of inflammatory cells, with varying amount of fibrosis. As a type of inflammatory pseudotumer, eosinophilic cholangitis or eosinophilic pseudotumor are extremely rare, and characterized by eosinophilic cholecystitis and associated extrahepatic biliary obstruction. Herein, we report a case of an eosinophilic pseudotumor of the bile duct in a 37-year old man who was referred to Eulji University Hospital for evaluation of jaundice. From cholangiography and a CT scan, intrahepatic duct dilatation and common hepatic duct obstruction were detected, therefore, common hepatic duct cancer was suspected. After percutaneous biliary drainage, he underwent an operation for bile duct resection and a hepaticojejunostomy. The final pathological finding was that of cholecystitis, with eosinophil and wall thickening of bile duct, accompanied by eosinophil infiltration and fibrosis, which was compatible with eosinophilic pseudotumor. The patient had no subsequent remarkable postoperative course and was discharged with normal liver function.
