Biliary tuberculosis mimicking cholangiocarcinoma: treatment with metallic biliary endoprothesis.
A 58-yr-old patient who presented with obstructive jaundice was evaluated with ultrasonography (US), computed tomography (CT), and percutaneous transhepatic cholangiography (PTC). Diffuse irregular stenosis of the extrahepatic bile ducts and periductal ill-defined soft tissue density along the hepatoduodenal ligament was determined. The patient was originally misdiagnosed with cholangiocarcinoma and, because the extent of disease process made surgical bypass impossible, was treated with a percutaneously inserted metallic stent. Histopathological examination of the endoluminal biopsy revealed ductal tuberculosis (TB). Most of the previous reports in the literature indicated that biliary obstruction was due to enlarged tuberculous lymph nodes compressing the bile duct. To our knowledge, only three cases of biliary stricture due to tuberculous involvement of the bile ducts were reported previously. This case illustrates the importance of tissue diagnosis in all cases of obstructive jaundice to avoid missing rare but curable diseases.
