Hilarinlfammatorypseudotumormimickinghilar cholangiocarcinoma

摘要

BACKGROUND: Inlfammatory pseudotumor of the biliary tract is a benign disease, and is extremely rare. Its diagnosis often depends on pathological examination after operation. The histopathological examination shows inlfammatory lesions with a polymorphous inifltration and variable amounts of ifbrous tissue. This study was undertaken to elucidate that an inlfammatory pseudotumor in the right hepatic duct is especially dififcult to distinguish from hilar cholangiocarcinoma. METHOD: The clinical data of one patient with inlfammatory pseudotumor of the right hepatic duct were analyzed. RESULTS:An occupying lesion of the right hepatic duct was revealed by abdominal ultrasound and magnetic resonance cholangiopancreatography. The right hepatic duct inlfammatory pseudotumor was not identiifed during the operation but was conifrmed by postoperative histopathological analysis. The patient recovered well without any serious complication. CONCLUSIONS: The preoperative evaluation for optimizing surgical management is important to the diagnosis of hepato-biliary occupying lesions. The evaluation involves clinical manifestations, imaging appearance and tumor markers. Malignant tumors and possible benign lesions should be considered to avoid aggressive surgical treatment.
