Inflammatory pseudotumor of intrahepatic biliary tract

Hepatic inflammatory pseudotumors are rare, presenting with a severe clinical pattern mimicing neoplasm. The diagnosis is almost always based on pathological examination showing inflammatory lesions with a polymorphous infiltrate and variable amounts of fibrous tissue. Development in the biliary tract is rare. We report the case of a 53-year-old patient who was referred for poor general condition and jaundice; the initial diagnosis tvas cholangiocarcinoma. Pathological examination of the surgical specimen showed a right intrahepatic biliary duct inflammatory pseudotumor. The patient developed recurrent jaundice three months after surgery due to a lesion of the left biliary ducts. Treatment with cortisone resulted in rapid improvement of jaundice.
